Therefore, it is important to study the optimization of TBM tunneling technology. Since the study of the optimization technology is still neo in many finelds of TBM tunneling, it is necessary to study this subject and ultimately apply the result of study to real projects. Based on the result of system engineering analysis tor TBM tunneling, we should focus on solving the optimization problems that relate to capital spending. Construction methods and TBM machines . This is the reason why we paid special attention in this article to the selection of TBM machines and related construction methods . By applying both the leveling method of Operations Research and ESQ method of System Engineering , the TBM Tunneling Decision Aids model and its program (TBMT-DAM) have been set up based on my extensive research and experience in this field. Thanks to the TBMT-DAM, it becomes possible for the construction specialist’s knowledge to be adopted in the early stage of the TBM project for and its related construction methods selection. This is crucial to guide the selection of TBM and its related construction methods effectively . From the point of view of technological economy, the proper selection of TBM will influence the success of TBM tunneling . Although this subject represents the most important aspect of TBM tunneling, relevant theoretincal research is still rare . This article thus provides new research results for the TBM tunneling field. TBM(Tunnel Boring Machine) driven tunneling technique would be expected to be developed towards larger cross section,hyper deep depth,and longer distance,with many technical problems having been resolved or being resolved.Mitsubishi,Kaoasaki,IHI lf Japan and Germany’s Herrenknecht have all made continuous innovation and success in R&D and manufacture of shield machines in terms of large cross section and copy profiled section. Entering the 21 century, China has since been seen a high tide of urban traffic tunnel project construction,by introducing successively shield tunneling technology and engineering technique of advanced world level,ad more than 40 shields are tunndling Metro tunnels where technical advancement and development have been gained in the aspects of project design,lining design,testing and study,construction technology,engineering monitoring&measuring,environmental safety or others for which 19 lecruies were made concerning Metro tunnel construction. The first in China DOT shield deployed in running section ,Shanghai Metro Line 8, has been thrusting forward at a speed 5-6m/day .Due to efforts made by technical people and tunnellers of STEC. China becomes the world’s second country to grasp the construction technique of DOT tunnel. In a near future triple 0 or multiple 0 tunnels might be snsking through China’s ancient land. China’s first DOT shield aooears to be a pair of strapped conventional shields, with superior functions incomparable to conventional shield’s . After one thrust by DOT shield, two tubes (upperbound and lowerbound) would be completed with work efficiency out of question . DOT tunnel occupies less under ground space than the conventional one , efficiently sauing space resource,and protecting environment,besides,the ability with which the shield can probe its way within narrow space between buildings is also superior than that of conventional one. The most important point rests at the place where two tubes intersects,as a natural 48cm passage is generated at each 1.5m spacing to allow one adult person passing through .Once shoud there be afire alarm or the like hazardous situation,people escape and rescue can easily be auailable,thus enhancing the safety of tunnel . In some cases, there are outstanding differences of rock property between the upper and the lower in a running section, for example, the upper medium is very soft while the lower very hard, even there are some hard rock er rock body scattering in the soft stratum. In that case, probably it is not the best choice to use shield tunneling method to construct the tunnel in terms to technicality, economic and scheduled progress. Acoording to different conditions, we could properly adopt some traditional means to solve those kinds of problems in shield tunneling project. Scentisis from analysis of each construction node for different TBMs, establishes different optimized models of rail transportantion proposal during tunneling by different types of TBMs. The basic thinking of optimized analysis is to find the most time saving branch off spacing, then to analyze further cost effectiveness tor different proposals, leading to find out the most money saving transportation proposal. During the process of modeling, scentists have fusde together multi-targer optimization theory,construction cost analysis method of TBM tunneling , with specific construction technology, therefore he gers at hand optimized model of rail track transportation methods tor TBM, Hydroshield , and Double shield TBM. Since by utilizing EXCEL programming, it makes much easier for application of optimized programme in horizontal transportation system duiing tunneling. The optimized programme has taken up analysis and design of shields both domestic and overseas. A tunnel boring machine (TBM) typically consists of one or two shields (large metal cylinders) and trailing support mechanisms. At the front end of the shield a rotating cutting wheel is located. Behind the cutting wheel there is a chamber where, depending on the type of the TBM, the excavated soil is either mixed with slurry (so-called slurry TBM) or left as-is. The choice for a certain type of TBM depends on the soil conditions. Systems for removal of the soil (or the soil mixed with slurry) are also present. Urban tunneling has the special challenge of requiring that the ground surface be undisturbed. This means that ground subsidence must be avoided. The normal method is doing this is to maintain the soil pressures during and after the tunnel construction. Although a great deal of research on TBMs have been published, and the applicability of TBMs has been discussed, considerable differences in opinion still exist between authors .The assessment of the feasibility of TBM tunneling is often complicated by the large number of parameters that should be taken into account .Tunnel Boring Machine efficiencies and capabilities have been tremendously increased in the last fifteen years, and the possibilities today are greatly different from those that existed in the seventies and eighties when the old plans for a Mediterranean Sea-Dead Sea canal and tunnel project was proposed and abandoned because of political and economic concerns. Today, according to the most experienced tunnel boring experts, it is possible to build a segmented concrete lined tunnel of ten meter inside diameter from Palmahim to Nahal Avnat for approximately one billion US dollars. Refer to the tunnel estimates link under design concepts to see an estimation prepared by the senior tunnel design engineer of Halcrow Group Ltd, UK .The whole section tunnelling machine of a new generation of our country is developed successfully in the second heavy-duty mechanical group company of China, this indicates our country has already reached the advanced international standards on this kind of equipment manufacturing field. According to the introduction of relevant experts of dual group, the whole section person who tunnel used in underground tunnel intelligent to equip in a complete set while being full-length specially, can one excavate shaping, strengthen the cement to the tunnel at the same time , make the rock tunnel project say good-bye to " tunnel tunnel ", old method on punch a hole to set off firecrackers ", have fast, safe, high-efficient, characteristic of environmental protection. First sets of products 3.65 of diameter, tunnel speed can up to 180, use quilt for Yunnan palm turtledove' s river diversion works every 24 hours. The expert estimates , such projects as the national railway , highway , water conservancy , oil gas , municipal administration ,etc. need to finish tunnel of 5800 kilometers altogether in the following 20 years. For a long time, the tunnelling machine that our country uses relies on the complete machine to introduce . A new generation the whole section appearance of person who tunnel is it reduce of our country tunnel construct the cost to contribute to, have wide market prospects. The coal mine anchor man pole bore drills into the development prospect of the equipments Stock is it is it have suitable to accelerate well lane tunnel speed , raise roof prop up result of protecting , is it prop up labour intensity of partial toing and reduce and prop up and protect the advanced technology that materials consume to reduce to protect to prop up. Our country country colliery tunnel 5 million more than tunnel every year with particular emphasis only, will it be the end 1997, stock prop up average to up to 31.5% the whole country of protecting etc., according to planning, by 2000, the stock should be up to 50% equally while propping up the protecting rate, but already such 16 mineral bureaus as Da Tong , Xingtai , Pingdingshan , iron processes , Western Hills , Longkou ,etc. have taken the lead in making the stock prop up the protecting rate and exceed 50%. Foreign advanced person mine country stock prop up partial toing rate exceed 80% often. Stock hole creep into it is stock that prop up important link constructed to protect, stock prop up protect development need a large number of stock hole creep into equipment guarantee. The hole of the stock creeps into the equipment and includes the stock rig and related drilling tool (drilling rod , bit ,etc.). It is analysed that the hole of stocks creeps into the current situation of the equipment , look forward to its development prospect , contribute to promoting the hole of stocks to creep into the technological progress of the equipment constantly, make it meet stocks and prop up the need which protects technology. The hole of the stock creeps into the equipment and relies mainly on stock rig . Stock rig divide the single style into, get into the train type, airborne type according to the structure; Divided into a battery operated , pneumatic type , hydraulic pressure type according to motive force; Divided into turning round type , impacted , striking the turning round type , turning the impacted round according to the broken rock way. Drilling tool related to stock rig , because broken rock ways are different different, have broken rock drilling tool , bludgonning into type broken rock drilling tool of turning round etc. and turn the striking type broken rock drilling tool round generally speaking. Foreign stock hole creep into variety and various function of equipment , superior technical feature have, dependability is high. 3 collieries of stock holes creep into the future of the equipment: Stock hole creep into equipment whether stock is it protect desirability of development to prop up, it must develop forward according to sure law, research , development , production and using of stock rig and related drilling tool , must accord with the objective law . Analyse domestic and international relevant information, summarize the experience and lessons , notice that the stock hole creeps into the tending to basically of equipment development in the colliery, help to make the products develop constantly in the market competition. 3.1　Pneumatic, the single turning round type stock rig of hydraulic pressure is a mainstream of one period; 3.2　Study stock rig torsion and reform bit development person who turn round stock hole creeps into the key to the equipment; 3.3　Development of new and high technology, is it should creep into change of technology on stock hole to haveIn these decades, the hole of the stock has already to creep into the equipment had certain improvement, with the development of kownledge economy, stock rig and related drilling tool will be improved to some extent gradually, it is estimated that can cause the great change of the products in the following: (1)Structure optimization and Hi-Tech new application of material of parameter, make single stock rig performance raise, weight lightens. Have adopted the rock bit of the new and high technology to make the turning round type creep into the way and expand the range of application. (2)Application on different power , different kinds of stocks rig of the Hi-Tech microelectric technique , may make stock rig take place some fundamental change , for example change rig characteristic , is it operate performance , raise dependability ,etc. to improve. Probe into stock hole that computer control creep into with comprehensive automation equipment that stock install already abroad. Success of the rock drilling robot uses and will promote the hole of stocks to creep into the progress of the equipment effectively. (3)Stock hole creep into development of equipment , is it protect technology and rock drilling foundation of developing into of technology to prop up with stock, stock is it protect appearance of new type , new material will put forward the new request to stock structure parameter , technical feature and function of rig to prop up. Stock hole development of rig must follow closely stock prop up the technical development partial toed. Meanwhile, the development of rock drilling technology will promote the hole of stocks to creep into the improvement of the equipment. Different rock drilling research and in common use rock drilling research results of machines of way, transplant to stock hole creep into development of equipment come up in time. (4)Stock hole creep into equipment whether stock prop up key equipment that protect, it influence stock prop up the quality partial toed --Install quality in position , accuracy and stock of the depth , aperture of the hole of the stock, personal security, labour intensity and homework terms related to operator again. Stock hole creep into core of equipment high-efficient and security. Develop colliery stock hole creep into equipment regard high- efficient , security as the core , there is powerful competitiveness , this is base with development prospect of a product.
