摘要
TBM完成掘进施工任务后,如何解决就地拆解TBM并运输出洞问题,以及能否快速、安全、经济地完成不良地质段超大断面拆卸洞的开挖及衬砌等工作对TBM的收尾工作就显得非常重要。以兰渝铁路西秦岭特长隧道左、右线2台TBM拆卸洞的施工技术作为研究对象,对其施工方案及其技术经济效果进行了实证对比分析,得出了具有一定参考价值的研究结论。
After TBM completes tunneling construction task,how to solve the on-site disassembly and transportation of TBM out of the grotto,and whether it can complete large cross-section demolition grotto excavation and lining quickly,safely and economically are important. This paper catch out railway line left,right 2 TBM disassembly grottoes which the West Qinling Mountains tunnel on Lanzhou to Chongqing as the research object,the construction scheme and technical economical effect was compared and analyzed,some referenced conclusion was put forward.
