在长大隧道的施工中,TBM法是目前较先进、较安全的一种隧道开挖的施工方法,并且在秦岭Ⅰ线隧道的施工中得到了很成功的应用,但目前为止,TBM法施工并没有得到很广泛的应有,主要原因还是TBM法的适用范围太窄,在通过不良地质地段时,TBM法施工遇到的问题很多。以南疆线中天山隧道为依托,总结了不良地质对TBM施工的影响,并对TBM法通过不良地质地段时采用的支护方法进行了研究和总结。
In the construction of long tunnels, TBM method is more advanced and safer construction method of tunnel excavation, and has been successfully applied in the construction of Qinling Ⅰ tunnel, but so far, TBM method construction The main reason is that the applicable scope of the TBM method is too narrow. There are many problems encountered in TBM construction when it passes through the bad geological sites. Relying on the Middle Tianshan Tunnel in the southern Xinjiang Uygur Autonomous Region, the influence of adverse geology on the TBM construction is summarized. The support method adopted when the TBM method passes the unhealthy geological section is studied and summarized.
