摘　　要：驷马山分洪道高切岭段渠道因其特殊地形地貌条件,且渠坡揭露地层具膨胀性,历年来屡次发生滑坡现象。本文通过分析其滑坡的特点和成因,并在高切岭段右岸渠坡选取典型断面进行勘测评估,探索一种膨胀土边坡勘察的方法,分析膨胀性土边坡滑动带或潜在滑动带的发育深度和力学特性,在此基础上根据边坡特点进行稳定性分析,为膨胀土边坡的阻滑防治提供参考。Due to special conditions in the topography and landforms,and to the expansiveness of the stratum exposed by the channel slope,landslides have occurred repeatedly in the Gaoqieling part of the Simashan flood diversion channel over the years.In this paper,by analyzing the characteristics and causes of the landslides,and surveying and evaluating the typical section of the right bank channel slope in the Gaoqieling part,a method of investigating the expansive soil slope has been explored for understanding the development depth and mechanical characteristics of the sliding or potential sliding zone of the slope.On this basis,the stability analysis has been carried out according to the characteristics of the slope,which provides a reference for making relevant control measures.
