Analysis on the Rainfall Seepage Characteristic and Stability of Mine Slope with Weak Interlayer Based on Numerical Simulation
In order to study the variation law of seepage characteristics and stability of mine slope under rainfall conditions,this paper takes a mine slope with weak interlayer as the research object.Based on the finite element software,the variation law of key parameters such as pore water pressure change,rainwater infiltration depth and stability coefficient of slope is analyzed under different rainfall conditions.The results show that the longer the rainfall duration and the greater the rainfall intensity,the greater the cross-sectional pore water pressure at the top of the slope and the deeper the rainwater infiltration depth;the slope stability coefficient gradually decreases with the increase of rainfall duration.The research results have certain theoretical and practical significance for improving the safety and reliability of mine slope engineering.
