基于Plaxis的土质边坡稳定性影响因素分析

Soil slope stability factors analysis based on plaxis

土质边坡在地质工程活动领域的出现越来越多,而准确的了解边坡的安全性如何以及土体的各项参数对其稳定性有何影响就更为重要。本文首先验证了有限元软件plaxis利用强度折减计算边坡安全系数的可行性,在此基础上,采用正交试验的方法分析了土体各项参数对边坡的稳定性影响作用的大小,为工程建设中边坡开挖设计和加固方案提供了依据。

Soil slopes in the field of geological engineering activities appear more and more,while accurately understanding of how the safety of slope and the parameters of soil impacting on the stability of homogeneous slope is more important.In this paper,the author verified the feasibility of finite element software plaxis by strength reduction calculating the safety factor of slope in the first place,and on this basis,used the method of orthogonal experiment to analyze the various parameters of soil on the effect of slope stability,providing a basis for excavation and reinforcement design in project construction.
