掘进机法

秦岭特长隧道是在我国铁路隧道中首次采用掘进机法（TBM）施工的隧道。

Qinling tunnel is the first railway tunnel which the TBM has been employed in China .

另外，随着隧道掘进机法的日益发展，为充分发挥其优点，与之对应的隧道结构较多采用装配式预制管片衬砌。

In addition , as the increasing development of tunnel boring machine method , to give full play of its advantages , fabricated precast segment lining are often used in building the tunnel structure .

长大深埋高水压山岭隧道的施工将越来越多地采用隧道掘进机法。

Mountain tunnel construction with high water pressure will apply the tunnel boring machine method ( TBM ) more and more .

本文着重论述了用钻眼爆破法和联合掘进机法掘进水平巷道现状，并指出了发展方向；

This paper emphatically discusses the present situation of drifting with methods of drilling-blasting and combined drifting machine and points out the direction of its development .

研究了岩石掘进机的工作原理、组成结构与分类，分析比较了掘进机法和钻爆法的优缺点，并探讨了掘进机法施工的基本适用条件和工作特点。

The main points of this dissertation are as follows : ( 1 ) The operating principle , the composition structure and the classification of TBM are studied . The advantage and disadvantage of TBM and those of drilling and blasting method are discussed and compared .
