摘　　要：新塘滑坡是清江水布垭水利枢纽水库区一巨型顺层深层基岩滑坡(体积5.08亿m3),其规模之大实属罕见,引人瞩目。本文通过对地质调查资料的系统总结,阐述了新塘滑坡的基本地质背景与基本地质特征,利用工程地质学与岩体力学理论与方法分析了滑坡形成的地质成因与力学机制,可作为多夹层、多剪切带的缓倾顺向坡结构边坡工程勘察与研究的参考。The Xintang landslide, with the volume up to 0.508 billion m^3 , is the deep-seated ancient rockslide type in Shuibuya Reservoir. This paper summarizes the investigation data and presents the geological settings and the geological characteristics of the sliding body. Using the theory and the methods of the engineering geology and Rock Mechanics, the mechanisms of the sliding was analyzed. The study methods used for this landslide can be adopted to investigate other similar dip slope with soft and shear zones.
