摘要
随着中国基础设施项目的不断展开,在水利、公路、桥梁等工程中都会遇到各种复杂的边坡问题处理。文章以某边坡为研究对象,采用三维数值分析方法,建立数值仿真模型,计算并分析地震作用对土质边坡稳定性的影响和失稳原理。基于地震超载法计算不同地震水平加速度下该边坡的安全系数,验证边坡稳定性,研究成果对地震作用时土质边坡的稳定性分析具有一定的指导意义。
With the development of infrastructure facilities projects in China, there are all kinds of complex slope problems in water conservancy, highway and bridge projects. This paper takes a slope as the object studied, adopting the three-dimensional value analysis method to establish the simulation model, to calculate and analyze the effect of seismic roles on soil slope stability and the theory of losing the stability. The seismic overload method was adopted to calculate the slope safety coefficients in different seismic acceleration to verify the slope stability, and the results show that the seismic roles have a certain guidance meanings for analysis of the soil slope stability.
