| 摘 要： | 从岩体宏观连续性假设出发,引入岩体表征单元体(REV)概念.首先根据岩块的三轴与卸载回弹试验以及结构面的室内直剪试验确定其基本力学参数;然后以数值模拟试验方法,依据当岩体区域体积达到并超过岩体REV尺寸时其力学性质趋于稳定的变化规律,对岩质边坡岩体REV的存在以及大小进行确定;最后根据满足REV尺寸的三维模型最终计算出对应边坡岩体的力学参数.

| Abstract: | The representation elementary volume(REV)was introduced on the base of the hypothesis of macro-continuity of rock masses.Firstly,the basic mechanical parameters of rocks were measured by the conventional triaxial tests and unloading resilience tests,and the mechanical parameters of rock interfaces and joints were obtained by direct shear tests.Secondly,the existence and the dimension of REV were determined by the method of numerical simulation testing according to the rule that the mechanical character can ... |
