摘　　要：马岭镇垮山滑坡位于四川省雅安市名山区,受“4·20”芦山地震的影响,该滑坡发生变形。由滑坡区的地形地貌特征推测该滑坡可能为老滑坡,为查明滑坡目前发育的多处变形破坏是否为该老滑坡局部复活形成,通过工程地质测绘、勘探、试验以及详细调查,查明了滑坡变形均为浅表变形,未见深层滑动的迹象,因此判断其不是老滑坡,研究结果为类似老滑坡灾害的判定以及工程治理提供了参考依据。The collapse landslide of Maling Town is located in the famous mountain area of Ya an City,Sichuan Province.Affected by the“4.20”Lushan Earthquake,the landslide deformed.According to the landform characteristics of the landslide area,it is speculated that the landslide may be an old landslide.In order to find out whether the multiple deformation and damage developed by the landslide are caused by the local reactivation of the old landslide,through engineering geological mapping,exploration,test and detailed investigation,it is found that the deformation of the landslide is shallow deformation,and there is no sign of deep sliding,so it is judged that it is not an old landslide.The research results are as follows:it provides a reference for the determination of similar old landslide disaster and engineering treatment.
