Research on Landslide Accumulation Mass Stability at a Hydropower Station

Abstract:

Landslide stability is very important to the hydropower station construction. The volume of landslide accumulation mass in a hydropower station was more than 47, 500, 000 m³, it was a large landslide accumulation body rarely in the history of hydropower engineering. As a research object, the landslide accumulation mass in this hydropower station was divided into three parts by geologic ingredient, which included bedrock, slip soil and accumulation mass. According to mechanical parameters such as internal friction angle, cohesion, natural unit weight and saturated unit weight obtained by some research, limit equilibrium method was adopted to analyze the slope stability. Accumulation mass safety factors in different parts were calculated, the destruction style was illustrated and landslide accumulation mass stability was also analyzed. The results show under normal condition, rainstorm and earthquake condition, the safety factor cannot meet the specification requirement. The research provides meaningful reference to design and construction in similar hydropower station.
