    碎石土边坡中地下水作用的稳定性计算方法分析

    THE EFFECTS OF GROUNDWATER ON STABILITY IN GRAVEL SOIL SLOPES

    • 摘要: 地下水对边坡的稳定性有多方面的影响,其中静水压力和动水压力在稳定性计算中如何考虑一直存在歧义。本文以三峡库区巴东县新县城西五路中段某边坡为例,分别考虑孔隙水压力与渗透力的作用,通过不平衡推力法计算边坡稳定性,获得不同计算结果,并与理正软件计算结果比较分析,得出暴雨工况下的碎石土边坡,在浸润线以下考虑渗透力作用更为符合实际状况且简化问题,而一些规范中孔隙水压力与渗透力同时考虑的规定是不合适的。

       

      Abstract: The groundwater has many effects on stability in gravel soil slopes. There are some different views on how to consider the effects of the pore water pressure and the penetration on stability assessment. This paper focuses on the different effects of the pore water pressure and the penetration in the stability calculation. Based on the results of the analysis on the Xiwulu slope in Badong county, it's more effective and available to consider the penetration and the effective bulk density below the saturation line in the heavy rain conditions. In some standards, the pore water pressure and the penetration are both considered on the stability calculation is inappropriate.
