充水作用下露天煤矿内排土场边坡稳定性分析
Slope stability analysis of open-pit coal mine dump under water filling
摘要
Abstract
In order to analyze the influence of water filling height on the stability of the inner dump slope when the abandoned mine is transformed into a water storage lake,the stability of the inner dump slope under different water level heights was studied by means of indoor similarity test,numerical simulation and theoretical analysis.The results show that with the increase of water filling height,the migration velocity of saturation line,the maximum displacement of slope,the pore water pressure and the pressure of slope soil are increasing as a whole.The larger the water filling height,the larger the slope inclination angle,and the lower the slope stability coefficient.The research conclusions provide reference for the transformation of open-pit coal mine into water storage lake or energy storage hydropower station project.关键词
