| 摘 要： | 通过在特定的应力水平上,利用Roclab软件,将非线性的Hoek-Brown强度包线转化为与之相匹配的Mo-hr-Coulomb强度的等效粘聚力和内摩擦角,然后采用有限差分软件对一均质岩性边坡算例进行分析,并与传统的极限平衡法相比较,结果表明:非线性的Hoek-Brown强度准则能有效地应用于工程岩体的数值模拟。

| Abstract: | This paper uses the Roclab software to transform the misalignment Hoek-Brown intensity enveloping curve as the Mohr-Coulomb intensity equivalent cohesive force,the internal friction angle of which matches it.then the finite difference software is used to make an analysis of isotropic lothological side slope examples,and is compared with the traditional limiting equilibrium method.The misalignment Hoek-Brown intensity criterion can be applied effectively to the project rock mass numerical simulation. |
