摘要:

为解决双线软岩隧道施工中普遍存在沉降和收敛过大、初期支护变形侵限导致拆换拱的现象,通过介绍兰渝铁路两水隧道施工中应用的几种工法,根据围岩监控量测数据分析,从安全、进度和设备利用方面进行比选,得出大拱脚台阶法比较适合于双线软岩隧道的施工。

关键词: 软岩隧道, 变形控制, 监控量测, 大拱脚台阶法

Abstract:

Serious settlement, convergence and deformation always occur during the construction of doubletrack railway tunnels located in soft ground. 3bench 7step construction method, CRD construction method and enlargedarchfoot bench method are adopted in the construction of Liangshui tunnel on LanzhouChongqing railway. These three construction methods are compared in terms of safety, advance rates and equipment availability. It is concluded that enlargedarchfoot bench method is more suitable for the construction of doubletrack railway tunnels located in soft ground.

Key words: tunnel in soft ground, deformation control, monitoring, enlarged arch foot bench method
