不同降雨模式下土质边坡渗流场分析的数值模拟研究
摘要
Abstract
In order to accurately analyze which rainfall mode has the greatest influence on the seepage field of soil slope among short-term heavy rainfall,long-term weak rainfall and periodic rainfall,according to the corresponding relationship between the permeability coefficient of unsaturated soil and the permeability coefficient of saturated soil,we use FLAC3D software to monitor the groundwater level in the process of rainfall infiltration,and use fish language to update the permeability coefficient of unsaturated soil in real time,and then determine the variation law of seepage field in the slope.The change of soil water content on the slope was monitored in the Pinglu Canal slope project in Guangxi,and the numerical simulation results were compared with the field test data to verify the reliability of the numerical simulation results.Through the numerical simulation analysis program proposed in this paper,the seepage characteristics of unsaturated soil on the slope under different rainfall modes are drawn,and the research results guide the slope engineering to formulate the support scheme in the process of rainfall.关键词
