土质边坡非饱和渗流及其稳定性研究
Study on unsaturated seepage and stability of soil slope
摘要
Abstract
In order to study the overall seepage field and stability changes of the soil slopes during rainfall and after the rain stops,numerical simulation analysis is carried out by using FLAC3D,and the simulation results are verified by using outdoor rainfall simulation tests.The results of the study show that rainfall infiltration process from the foot of the slope began to damage,mainly in the form of shallow sliding;during the rainfall cessation of the initial period,the rain will continue to infiltrate,the depth of the wetting peak continues to move downward,and the coefficient of safety still has a tendency to decline;In the mid to late rainy season,the factor of safety begins to pick up as the soil moisture decreases;the increase in rainfall intensity and slope gradient is detrimental to slope stability.The research results provide a new idea for solving the unsaturated soil flow-consolidation coupling problem.关键词
