全断面掘进机施工隧洞缺陷的综合治理

通过工程实践,较详尽分析了全断面掘进机（TBM）施工隧洞常见缺陷的成因,简要总结了管片渗漏、裂缝、错台及不良地质洞段缺陷处理的一般方法,具体介绍了一些新型修补材料和较为成功的缺陷处理经验,可供类似工程建设借鉴。

Comprehensive Treatment to Deal Defect of Tunnel Constructed By TBM

Based on the practice of projects,this paper analyzed the common causes of defect in tunnels constructed by TBM in detail.The general methods to deal with seepage,crack,unevenness of joints on the lining blocks and defect of tunnel in poor geologic conditions are summarized.The new materials to mend tunnel are introduced concreately,and some successful experiences on the defect treatment of tunnels are introduced too.These experiences will provide the reference to other similar tunnel project.
