| 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。

| 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 ... |
