摘    要:根据工程地质性质和砂岩、板岩比例对隧洞区工程地质岩组进行了划分,并对结构面和岩体结构进行分级和分类,在此基础上用T系统和RMR系统对隧洞围岩进行分类;变形计算中,根据围岩分类,采用基于GSI的Hoek-Brown经验方法对围岩岩体变形进行分析计算,并根据围岩分类和变形计算,对TBM在西线的适用性进行了探讨。

关 键 词:岩石力学 围岩分类 工程地质岩组 围岩变形 Hoek-Brown判据

Abstract:According to the engineering geological conditions and the proportions of the sandstone and the slate,the strata in the tunnel area are divided into different parts.The rock mass and the structural planes are classified into different species.The rock near the tunnel is then classified using the T system and the RMR system.The deformation of surrounding rock is calculated and analyzed according to the Hoek-Brown method based on the geological strength index(GSI).By classifying the surrounding rock and calculating the deformation,the tunnel boring machine(TBM) applicability in the west route of South-to-North Water Transfer Project is discussed.
Keywords:rock mechanics   surrounding rock mass classification   engineering geological petrofabric  deformation of surrounding rock   Hoek-Brown criterion
