Abstract
Based on the metro high fill slope of Jin'ao Temple Depot in Chongqing,the limit equilibrium method was used to simplify Bishop method,Morgenstern-Price method and midas-GTS finite element software.Considering the influence of slope top load,seism and groundwater level rise in slope,the stability coefficient of high fill slope was analyzed and calculated.The result shows that,the permanent fill slope meets the stability and safety requirements under general working conditions and seismic conditions.However,the rainfall action leads to the increase of the groundwater level in the slope.When the buried depth of the water level in the slope is higher than 7.75 m,the slope stability coefficient will be lower than 1.35,which does not meet the design safety value of the permanent slope.To ensure the safety of the slope,it is necessary to control the groundwater level in the slope by strengthening the drainage in the slope and the water interception outside the slope.关键词
