摘要
通过对隧道衬砌裂损变形破坏原因的分析,分别对隧道拱部、边墙、侧沟采取针对性的整治措施,提出隧道衬砌加固前采用临时支护的必要性,并对影响施工进度的因素进行优化。
Based on the exploration of the causes for the lining split and deformation of the railway tunnel,treatment measures are taken to deal with the arch,the sidewall and the side ditch of the tunnel respectively.This paper puts forward the necessity of applying temporary support for tunnel lining before permanent consolidation,and presents methods to optimize the construction schedule.
