| 摘 要： | 针对目前边坡稳定性计算中破坏准则均为Mohr-Coulomb破坏准则的情况,根据相关准则和原理,推导了基于Hoek-Brown准则的Morgenstern-Price法计算公式.该法克服了一般岩体边坡稳定分析中岩体强度参数纯经验取值的缺点,使计算更为精确、合理.采用具体算例进行对比,探讨了不同准则下边坡稳定性计算的差异原因,并运用基于Hoek--Brown准则的Morgenstern-Price法对安家岭露天矿北端帮滑坡进行了分析.

| Abstract: | The plastic criterion popularly used in slope stability analysis is the Mohr-Coulomb criterion.A formula based on the basic principles of the Hoek-Brown failure criterion and the Morgenstern-Price scheme was deduced.The disadvantage that data are empirically obtained in slope stability analysis is overcome by adopting this method and the computing results are more accurate and reasonable.An example was discussed to compare the slope stabilities with different failure criteria,and the stability analysis of A... |
