摘　　要：水电站地质灾害危险性分析一直以来都是水利工程建设中的研究重点,尤其是滑坡地质灾害,是云南分布较为普遍的不良地质现象。文章通过对泗南江水电站库区的地理地貌概况、地质构造、地层岩性、水文地质等资料进行综合研究,总结并分析库区滑坡的分布规律、规模、危害、活动特征、主要诱发因素等以及库区蓄水后滑坡对工程安全的影响,并对其进行危险性现状分析和预测分析。最后按危险性高Ⅰ、危险性中等Ⅱ、危险性低Ⅲ的标准对滑坡做危险性分区。针对滑坡危险性的高低,提出相应的防灾减灾建议,对泗南江水电站的建设具有一定的指导意义。The geological hazards analysis of hydropower station is always important in the hydraulic engineering construction. Especially the landslide geology hazard, it＇s the distribution of the more common unfavorable geological phenomena in Yunnan. Based on synthetic study on the geography landform information, geologic structural, formation lithology,hydrogeology of Sinan fiver hydropower station reservoir. This article mainly summarize and analyze the reservoir landslides＇ distribution rule, the scale, the harm, the active characteristic, the mainly induce factor as well as the security influence of the landslide to the project after the reservoir stores water. And the dangerous of the present situation analysis and the forecast analysis are made . Finally presses the dangerous to be high I , the medium Ⅱ and the low Ⅲ standard makes the dangerous district to the landslides. Contraposing the landslides dangerous height, this paper would put forward the proposal for the disaster prevention and relief. This article would be a certain instruction significance to the contruction of Sinan fiver hydropower station, simultaneously also provided the model for this kind of project landslide dangerous analysis.
