摘　　要：针对引红济石引水隧洞软岩变形情况,分析隧洞变形的主要影响因素。通过变形软岩试验,对矿物成分进行分析、天然密度和天然含水率测试及崩解性试验等综合分析得出隧洞挤压变形的主要原因。提出了变形软岩的加固方法及TBM在变形软岩中的施工控制措施,有效地解决了施工难题,可为类似工程的施工提供借鉴。In view of soft rock deformation of diversion tunnel of Yinhongjishi, the article is based on analysis of the main influenced factors. According to the soft rock deformation tests, it analyzes mineral composition, natural density,natural water content test and disintegration test and other comprehensive analysis and find out the main reason of extrusion deformation. It puts forward to the relative reinforcement method and the construction control measures of TBM during the deformation of soft-rock, effectively solve the construction problems, which can provide reference for similar engineering construction.
