马岭镇垮山老滑坡存在性分析

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。

Analysis and Research on Existence of Old Landslide in Maling Town

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 topographic and geomorphological characteristics of the landslide area, it is inferred that the landslide may be an old landslide. In order to ascertain whether the multiple deformation and failure of the landslide are caused by the local revival of the old landslide, the deformation of the landslide is found to be superficial deformation through engineering geological mapping, exploration, test and detailed investigation, and no sign of deep sliding is found. Therefore, it is judged that the landslide is not an old landslide, which is similar to the old landslide. The judgment of landslide hazards and engineering treatment provide a reference basis.
