摘要
随着我国经济的快速发展,交通基础设施的建设也在不断加强,其中,隧道工程更是表现出了"多、长、大、高、深"的特点,隧道工程建设难度越来越大,风险越来越高,TBM(岩石隧道掘进机)法应运而生.与传统钻爆法施工相比,TBM法具有机械化程度高、安全性好、施工速度快等优点,但因公路隧道断面较大,TBM法施工空间及造价要求较高等原因,目前在公路隧道中的应用较少.文章将从TBM施工平行导坑、TBM施工主洞超前导坑等方面阐述目前TBM法在山岭高速公路隧道施工中的应用.
Abstract
With the rapid development of China's economy,the construction of transportation infrastructure is also constantly strengthened.Among them,tunnel engineering is characterized by multi,long,large,high and deep.Tunnel engineering construction is becoming more and more difficult and risky.TBM(Tunnel Boring Machine)method came into being.Compared with the traditional drilling and blasting method,the TBM method has the advantages of high mechanization,good safety and fast construction speed.However,due to the large section of the highway tunnel and the high construction space and cost requirements of the TBM method,it is currently less used in the highway tunnel.This paper expounds the application of TBM method in the construction of mountain expressway tunnel from the aspects of TBM construction parallel guide pit,TBM construction main hole advance guide pit and so on.
