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.
基于等效Mohr-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。
Onthe basis of equivalent hypothesis,equivalent Mohr-Coulomb criterion bas been successfully applied to FEM software-Ansys by artificial conversion on jointed rock mass parameters,and all kinds of relation between the transformed parameters and original parameters are verified.
基于等效MohrOCoulomb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,并验证转化后参数与原参数之间的大小关系;同时针对边坡岩体流变特性,利用分数阶导数流变模型理论,提出考虑岩体流变特性的一种实用计算方法,通过Ansys弹塑性计算分析过程中改变材料特性的功能来处理边坡岩体材料的流变问题,算例表明该方法是可行的。
