摘　　要：文章针对边坡问题,分析了安全系数以及稳定性相关的主要理论,阐述了具体的计算方法,并且在锚杆支护的条件下,将锚杆上的作用力分解为法向分量和切向分量,引入安全系数的计算公式中;再以有限元分析法为基础,通过建模、划分网格、节点等效塑性应变计算等步骤,有效地确定了模型上的潜在滑动面。Aiming at the slope problem,the main theories related to safety factor and stability are analyzed,and the specific calculation method is expounded.Under the condition of bolt support,the force on the bolt is decomposed into normal component and tangential component,which is introduced into the calculation formula of safety factor.Based on the finite element analysis method,the potential sliding surface on the model is effectively determined by steps such as modeling,meshing,node equivalent plastic strain calculation.
