| 摘 要： | 根据简易纵剖面仪野外现场绘制的大量节理表面轮廓曲线的修正直边法测量结果,综合评价边坡岩体3个结构区12组节理沿走向方向和沿倾向方向的粗糙度系数,并在此基础上,运用JRC—JCS模型估算了各组节理沿走向和倾向的抗剪强度参数。通过对比统计估算和试验结果,确定节理抗剪强度取值标准,作为边坡岩体稳定性研究的计算力学参数。

| Abstract: | According to the survey results of a vast amount of surface outline curves of joints drawn on-the-spot-by using the method of reviced straight side and simple and easy longitudinal section device and,based onthe comprehensive evaluation of roughness coefficients of strike direction and dip direction of 12 groupsjoints of 3 structural regions of slope rock mass,the pater estimates the shear strength parameters along strikeand dip of each group joint by using JRC-JCS model.The paper sets a standard for taking the values of jointshear strength as the parameter of mechanics calculation of study on the stability of slope rock mass throughcomparing the result of statistic estimation and the result of test. |
