The Economical Evaluation Research And Construction Technique Scheme Of Long Tunnel With Large Section

In recent years, there are more and more constructions of long and large tunnels. The idea of realway striding developement has put up an ardent need about fast tunnel construction whose distinct specialty is"long"and"fast". Tunnel is very important in line construction and it can influnce the rate of total progress. It has become a hot topic that how to choose the better technical plan,the apt machine to form a complete set,and how to solve the problems under idiographic circumstance on the purpose of fast tunnelling.This thesis is based on the Wushaoling specially long tunnel and some correlative typical engineering examples.The author also take the third and the forth inclined well as examples. In the text I have done across-the-aboard and drastical research about how to optimize the technical plans, how to choose the apt machine to form a complete set, especially how to make the assistant holes operating in main tunnel construction and have put forward feasible scheme about the technical plans of the two transport methods that how to use the assistant holes in main tunnel construction. I also do some research about engineering ration and cost, about which the author put forward some special ideas. The author study out the economical evaluating model about how to choose the construction plans of inclined well with or without tramroad, to provide the referrence for future schemes of big tunnel construction.
