摘　　要：为了研究土质边坡在长历时大暴雨条件下的水力学特性演化机制,文章根据某土质边坡工程,采用SEEP渗流模块,基于数值模拟软件,对该土质边坡在长历时降雨过程中土体的水力学特性演化过程进行分析。结果表明,随着强降雨持续,边坡的负水压区域逐渐减小,边坡坡脚位置处的水压不断增大,水力计算经历了升-降的变化过程。结果可为类似土质工程边坡在长历时大暴雨条件下边坡稳定分析提供参考。In order to study the evolution mechanism of hydraulic characteristics of soil slope under the condition of long-term heavy rainfall,this paper adopts SEEP seepage module and numerical simulation software to analyze the evolution process of soil hydraulic characteristics during long-term rainfall is analyzed according to a soil slope project.The results show that the negative water pressure of the slope decreases and the water pressure at the foot of the slope increases with the continuous heavy rainfall.Hydraulic calculations went through a process of rising and falling.The results can provide a reference for slope stability analysis of similar soil engineering slopes under long-term heavy rainfall conditions.
