摘　　要：为了研究库水位下降速率与渗透系数对边坡渗流稳定的影响规律,运用Geostudio2012数值模拟软件和敏感性系数法,以八字门滑坡为研究对象,将库水位下降速率与坡体的渗透系数作为边坡渗流稳定的重要影响因素进行边坡的稳定性模拟和敏感性分析,确定了库水位下降速率与渗透系数对边坡渗流稳定的控制作用大小。结果表明:八字门滑坡的渗流稳定对库水位下降速率的变化更为敏感。In order to study the influence law of decline rate of reservoir water level and seepage coefficient on seepage stability of slope,Bazimen Landslide was taken as the object herein to carry out the stability simulation and the sensitivity analysis with the software of Geostudio 2012 by sensitivity coefficient method,and then determine the control action of both the decline rate and the permeability coefficient as the factors influencing the stability of landslide seepage.The result shows that the seepage stability of Bazimen Landslide is more sensitive to the decline rate of reservoir water level.
