中文摘要：

探讨了岩体本构模型之间的关系,通过材料参数的换算,实现了等效Mohr-Coulomb屈服准则在An-sys中的应用.借助有明显滑面的岩质边坡算例分析,验证了采用它来代替Mohr-Coulomb屈服准则是可行的,同时运用外角点外接圆锥Drucker-Prager屈服准则、等效Mohr-Coulomb屈服准则、极限平衡法进行计算,做了边坡稳定性及物理量随结构面参数变化的灵敏度分析、计算结果对比,得到了一些有益的结论,对有明显滑面岩质边坡稳定性分析及支护结构设计具有一定的参考价值.

英文摘要：

In this paper,the relation between rock constitutive models is investigated.With the conversion of material parameters,the application of Equivalent Mohr-Coulomb Yield Criterion in Ansys is accomplished.By analyzing the example of rock slope with obvious slide surface,the viewpoint that using Equivalent Mohr-Coulomb Yield Criterion to replace Mohr-Coulomb Yield Criterion turns out to be feasible.Also,using Exterior Angle Point Circumscribed Cone Drucker-Prager Yield Criterion,Equivalent Mohr-Coulomb Yield Criterion and Limit Equilibrium Method in calculation,some instructive conclusions that have certain referential value to supporting structure designing and stability analysis of rock slope with obvious slide surface,are arrived at by the comparison of results,analysis of the parameter sensitivity to the changes of structure interface and rock slope stability.
