浅析坡外水位下降影响尾矿库岸坡稳定性的主要因素

Analysis of the main factors influencing the stability of the bank slope of the tailings pond due to the drop of the water level outside the slope

本文建立数值模型,分析水位下降过程中尾矿库岸坡土体所受最大剪应力的变化情况及其稳定性变化情况,简要分析了尾矿库岸坡稳定性安全系数最小时刻的渗流情况。最后研究模型模拟的结后,尝试归纳了坡外水位下降影响粘性土质岸坡稳定性的主要因素。

In this paper,a numerical model is established to analyze the variation of the maximum shear stress and the stability of the soil mass on the bank slope of the tailings pond in the process of water level falling,and the seepage at the minimum time of the safety factor of the stability of the bank slope of the tailings pond is briefly analyzed.At last,the main factors that affect the stability of clayey soil bank slope are summarized after studying the model simulation.
