摘要
为保障降雨条件下公路路堑边坡运营安全,本文以某公路路堑边坡开挖工程为例,通过建立降雨条件下公路路堑边坡数值模型,对持续降雨条件下路堑边坡稳定性进行分析。结果表明,随着降雨时间持续,路堑边坡坡体的最大水平位移与最大竖向位移都呈现上升趋势,安全系数显著下降;降雨显著降低土体抗剪强度,使土体有效应力减小,可能引发浅层滑塌。研究结果为实际工程施工提供一定理论参考。
To ensure the operational safety of highway cutting slopes under rainy conditions,this paper takes a certain highway cutting slope excavation project as an example and analyzes the stability of the cutting slope under continuous rainy conditions by establishing a numerical model of the highway cutting slope under rainy conditions.The results show that with the duration of rainfall,both the maximum horizontal displacement and the maximum vertical displacement of the slope body of the cutting edge show an upward trend,and the safety factor decreases significantly.Rainfall significantly reduces the shear strength of soil,decreases the effective stress of soil,and may cause shallow landslide.The research results provide certain theoretical references for actual engineering construction.
