ANISOTROPY OF SLATE STRENGTH IN WEST ROUTE OF SOUTH-TO-NORTH WATER TRANSFER PROJECT

  • 摘要: 南水北调西线工程区域内岩体类型主要为砂岩、板岩,其中板岩强度特性具有明显的各向异性特征。研究复杂地质条件下板岩的强度特征及变形规律,确定合理的板岩强度参数,对于引水坝址的选取和深埋长隧洞的设计与施工都具有十分重要的意义。在南水北调西线工程选取钻孔采取的板岩岩样,通过单轴压缩变形试验和三轴压缩试验等室内试验方法,借助Hoek-Brown经验破坏准则,对板岩强度随板理面倾角的变化规律、板岩强度的各向异性特征进行了分析,并确定了合理的板岩抗剪强度参数。研究成果可为工程设计提供必要的基础资料。
