摘　　要：通过室内节理岩体直剪试验,得到节理面应力应变响应,以及剪应力和正应力之间的关系;然后根据Mohr-Coulomb强度准则计算相应粘结力和内摩擦角,并通过数据的工程处理将岩块参数转换为岩体物理力学参数,为进一步的计算分析提供数据基础。The direct shear test for joint rock mass is done in laboratory, the stress-strain responses are obtained as well as the relationship between shear stress and normal stress; According to Mohr-Coulomb criterion, the corresponding cohesion and friction angle are obtained, the physical parameters of rock mass are obtained by the engineering dealing method according to the parameters obtained from lab test, which will give further foundation for the calculation analysis.
