碎石含量对三峡库区滑坡体浸润线的影响
Influence of the Gravel Content on the Seepage Line of Landslide in Three Gorges Reservoir Area
摘要
Abstract
The gravel soil is the primary soil in Three Gorges Reservoir area and the existence of gravel will influence on the seepage line of the landslide by influencing on the permeable of the soil. Influence of the content of gravel on the seepage line of the landslide was researched by adopting the analytic mathematic statistics method. With the consequence, the influence of drawdown speed of water level with different hydraulic conductivity on the changing of the seepage line was analyzed by finite element method. As a result the seepage line of the landslide is closely related to the content of gravel. The seepage line shows the different characteristics in different contents of gravel. When the drawdown speed of water level in the reservoir is changed, the shape of seepage line in the same content of gravel is the same and it depends on the content of gravel. It is found that the drawdown speed has no effect on the seepage line in the content of gravel below 30 percent, but it has effect on the seepage line in the content of gravel above 55 percent. The impact area of water level variation on seepage line is on the top of the landslide.关键词
