摘　　要：在研究了三峡水库区兴山县电厂滑坡Ⅰ的工程地质及滑坡体基本特征的基础上,介绍了该滑坡的结构及变形特征。从滑坡形成条件、诱发变形因素两方面分析了滑坡形成的原因及诱发坡体失稳的主要因素;在诱发因素分析的基础上应用中国地质大学(武汉)研发的LaSa软件程序,对电厂滑坡Ⅰ进行稳定性分析计算。结果表明:在天然情况下,滑坡整体均处于稳定状态;在特定条件情况下,滑坡处于临界蠕滑或失稳状态。结合工程实际对滑坡治理进行初步研究,提出了一些可行的防治措施及建议。Power Plant landslide I is located in Xingshan county. Based on the study of engineering geological conditions and basic properties of the landslide, this paper describes the structure and deformation characteristics of the landslide and analyses its causes and main inducing factors. The comprehensive treatments of the landslide are also discussed. Using LaSa software developed by the China University of Geosciences （Wuhan）, we calculated the stability of the landslide. Results show that the landslide is stable under natural circumstance while it is in critical creeping motion and at the unsteady state when the landslide body in saturation or after impoundment of the reservoir. The advising countermeasures for the landslide were also put forward in this paper.
