Other AbstractIn every big flood, there will be a lot of landslide on both sides of the river, but currently flood process of landslide seldom research. In this paper, we based on the limit analysis theory, established landslide model of the curved surface under the action of flood, studied the effect of  flood water level, groundwater level, erosion quantity and other parameters effect on landslide stability, found that: along with the surface water level increasing stability coefficient of the landside increased, with the rise of groundwater level stability coefficient of landslide is reduced, under the double action of landslide groundwater and internal friction angle of soil, internal friction angle between 15 °and 25°, the landslide has a failure process. As the scour depth increasing stability coefficient decreased. As the slope increasing, the influence of depth of scour on the stability coefficient is reduced. Compared with other parameters, scour depth and angle of internal friction have a great influence on coefficient of stability.
