| 摘 要： | 基于等效Molar—Coulomb屈服准则原理，通过岩体材料参数的人工换算，实现其在有限元软件Ansys中的应用，并论证了转化后的材料参数与原参数的大小关系，即转化后参数恒比原参数小。结合算例分析，得知采用等效Molar—Coulomb屈服准则计算得到的岩质边坡安全系数偏小、保守，可用来模拟岩体材料；同时，对不同位移及应力工程精度要求的岩质边坡工程，提出采用不同屈服准则的建议。

| Abstract: | On the basis of equivalent hypothesis, equivalent Mohr-Coulomb criterion has been successfully applied to FEM software-Ansys by artificial conversion among rock-soil material parameters only, and the size relation between the transformed parameters and original parameters are verified, that is to say, the latter is bigger than the former. By the analysis of rock slope examples, we can know that the calculation result of slope safety coefficient by adopting equivalent Mohr-Coulomb criterion is little and conservative, and can be used to simulate rock-soil material. To different rock slope with different precision expectation of displacement and stress, we should adopt different criterion to simulate rock-soil material. |
