摘　　要：库区地质灾害的分布规律及今后的发展趋势对二滩水电站的运营寿命有着重要的影响。电站自1998年蓄水以来,库水位涨落、侵蚀基准面的抬高等变化,对库区地质灾害的稳定性和发展起到什么样的影响,是研究所要解决的主要内容。在实地收集资料的基础上,系统地分析和评价了库区地质灾害,为水电站下一步工作规划提供了重要的依据。Distributing law and evolution trend of geologic hazards at reservoir area has important influence on the life-running of ertan PowerStation.Since 1998 when the water-storage began,that fluctuation of reservoir water-level,arise of eroding datum plane,and etc,have what kinds of influence on the stability and development of geologic hazards at reservoir area,is the main matter which the institute should solve.Based on field-collected data,the geologic hazards at reservoir area were analyzed systemically and evaluated,and thus an important basis for the PowerStation＇s next working layout was provided.
