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 doubletrack railway tunnels located in soft ground. 3bench 7step construction method, CRD construction method and enlargedarchfoot bench method are adopted in the construction of Liangshui tunnel on LanzhouChongqing railway. These three construction methods are compared in terms of safety, advance rates and equipment availability. It is concluded that enlargedarchfoot bench method is more suitable for the construction of doubletrack railway tunnels located in soft ground.
Key words: tunnel in soft ground, deformation control, monitoring, enlarged arch foot bench method
