针对某厂房后边坡问题,采用非线性有限元分析方法,给出初始应力场、开挖、加固施工过程的数值仿真,岩体本构关系用弹粘塑性模型及新流变模型,按预应力锚索工作原理建立锚索模型,研究边坡塑性应变形成过程,以此过程分析提出边坡加固方案,并采用强度储备方法评价边坡稳定。 Aiming at the problem of slope after a factory building, the nonlinear finite element analysis method is used to give the initial stress field, the numerical simulation of the excavation and reinforcement construction process, the elastic-viscoplastic model and the new rheological model of the rock mass constitutive relationship, Anchorage cable working principle is established to study the formation process of plastic strain in slope. Based on this process, the slope reinforcement plan is proposed and the stability of slope is evaluated by strength reserve method.
