manyplaces developed a lot of landslide formed dams

some broke quickly

some existed for a long time.Landslide formed dams have a beautiful landscape and are hot visiting areas by tourists. The safety of thedams must be assessed before we develop and utilize the landslide formed dam areas. The paper studiesthe stability of a landslide formed dam. The calculated result proves that the dam is stable and does notpose danger to the hydropower station to be built and life and properties in the downstream.
