Study On Stability Of Landslide In Reservoir Area Of Xiangjiaba Hydropower Station

Xiangjiaba hydropower station is the most downstream of planning in the lower reaches of jinsha River hydropower station, which is planned in the Jinsha River downstream,the length of reservoir is156.6km. There are many old landslide in the reservoir area, and in the status quo conditions, the stability of the overall is general.But the slide stability of reservoir water has become the focus problem when the reservoir was filled.The title of this paper is the evaluation of the overall stability of Xiangjiaba hydropower reservoir,and based on the field survey,I have learned the main distribution reservoir landslide location, the type、features and the stability of landslide. Then choosed sample and carried out laboratory tests and finally could make a conclusion through resurrecting the typical landslide and studying the dynamics.At the same time, the results obtained have been used in engineering construction, and achieved good economic and social benefits.
