摘　　要：江淮分水岭高切岭段渠道因特殊的地形地貌条件,且渠坡揭露地层具膨胀性,历年来屡次发生失稳现象。通过分析膨胀土渠道滑坡的特点和成因,选取典型断面,采用连续取样钻探和静力触探进行勘测,分析边坡滑动带或潜在滑动带的分布位置、发育特点和力学特性。考虑滑动带或潜在滑动带,分别对边坡实施阻滑措施,并进行稳定性验算。通过对渠坡的稳定性和阻滑处理措施的研究,为膨胀土边坡的阻滑防治提供参考。Due to the special topographic and geomorphological conditions of the channel in Gaoqiel⁃ingsection of the Jianghuai watershed and the expansion of the stratum exposed by the channel slope,insta⁃bility has occurred repeatedly over the years.By analyzing the characteristics and causes of expansive soil channel landslide,typical sections are selected for continuous sampling drilling and static cone penetration survey,and the distribution position,development characteristics and mechanical properties of slope slid⁃ing zone or potential sliding zone are analyzed.Considering the sliding zone or potential sliding zone,the an⁃ti-sliding measures are carried out on the slope respectively,and the stability is checked.Through the study of the stability of the canal slope and the anti-sliding treatment measures,it provides a reference for the an⁃ti-sliding prevention and control of the expansive soil slope.
