库水升降对漩口滑坡稳定性的影响规律
Impact Rule of Reservoir Water Level Fluctuation on the Stability of Xuankou Landslide
摘要
Abstract
Variation of reservoir water level is a main factor to decrease the landslides stability in reservoir.In order to study the effect of reservoir water level on landslide stability,the paper takes Xuankou landslide in Zipingpu reservoir as an example.The Geo-Studio software was used to analyze the seepage field and stability of landslide with reservoir water level rising and falling.The numerical simulation was verified by the monitoring data of reservoir water level and ground displacement.The results show that the soil-water characteristic curve determined by the grading curve and the improved Kovács model could be used to simulate the seepage field.When water level is raising,the landslide's stability is increases with the rise rate of reservoir water level.When the water level is falling,the stability has two stages from decrease to increase.The moment of minim stability occurs at the lowest point of reservoir water level declines.Reservoir water level fluctuation on the stability is mainly affect the front of Xuankou landslide.关键词
