摘要: 漾濞县秀岭中村滑坡位于澜沧江水系漾濞江流域一级支流柏木铺沟左岸,属构造侵蚀中切割中山陡坡地貌,为一新生滑坡。在详细调查滑坡地质背景及变形破坏特征的基础上,采用不平衡推力传递系数法对滑坡参数进行反演及稳定性分析,认为暴雨和地震为滑坡失稳的主要诱因。调查研究表明该滑坡为降雨诱发小型牵引式浅层土质滑坡,其治理应以抗滑桩支挡结合地表排水为主。

Abstract: TheXiulingzhongcun landslide is located at the slope area of Baimupu gully in Yangbi River Basin of Lancang River watershed. The landside is a first time occurred slide caused by the tectonic erosion in the deep incised mountain valleys. A detailed geological background and landslide characteristics investigation was performed and the limit equilibrium analysis was conducted. The slide shear strength parameters were obtained. The analytical results concluded that heavy precipitation and the earthquake are the major triggering factors resulting the landslide. The site reconnaissance indicated that the slide is a typical heavy rain induce shallow failure. The caisson and surface drainage structure were used to remediate the failure.
