摘要
本文主要研究粉质黏土边坡在自重、降雨和相同参数下的边坡稳定性.分别运用两种软件进行数值模拟对比结果,选择安全系数更高的分析软件,以此作为数值模拟的方式.采用200 mm厚混凝土作为防护结构,模拟坡体在遭遇强降雨5 h范围内的边坡稳定性.分析结果显示,采用MIDASGTS进行数值模拟的边坡安全系数相比于FLAC3D的结果差异较小;在未降雨时,混凝土护坡对边坡稳定性影响不大;护坡状态下降雨5 h范围内,坡体内部孔隙水压和边坡稳定系数变化小.
This paper mainly studies the stability analysis of silty clay slope under gravity,rainfall and the same parameters.Two kinds of software were used to compare the results of numerical simulation,and the analysis software with higher safety factor was selected as the way of numerical simulation.200 mm thick concrete is used as a protective structure to simulate the slope stability within 5 hours of heavy rainfall.The analysis results show that the slope safety factor simulation by MIDASGTS is less different from that of FLAC3D.Concrete slope protection has little effect on slope stability during rainfall.Under slope protection,the change of internal void pressure and slope stability coefficient is small within 5 hours of rainfall.
