| 摘 要： | 降雨是引起边坡失稳的主要原因之一,降雨要素与边坡稳定性有着复杂的关系,其中降雨强度和降雨历时起主要作用。基于多孔介质流体力学、土力学等理论,考虑不同降雨要素对饱和-非饱和土质边坡稳定性的影响,建立了降雨条件下土质边坡稳定性流固耦合模型;采用Geo-slope分析软件进行了数值求解。通过数值仿真模拟,对降雨强度和降雨历时两个影响因素进行了深入分析,得出不同条件下土质边坡稳定系数,及其与降雨强度、降雨历时之间的关系;在对降雨条件下边坡稳定性模拟预测预报的基础上,通过降雨要素与土质边坡稳定性之间关系的分析,探讨了土质边坡的安全性问题,可以为有效指导土质边坡防护工作提供理论基础。

| Abstract: | Rainfall is one of the main causes of slope instability.There is a complex relationship between rainfall elements and slope stability.Rain fall intensity and duration play a major role.Based on hydrodynamics and soil mechanics theory of porous medium,considering the influence of different rain fall elements with the saturated-unsaturated soil slope stability,the paper established the soil-slope stability model for fluid-structure interaction under the condition of rainfall.We make a numerical solution with ... |
