Numerical Research on the Deformation Characteristics of a Reservoir Landslide
Reservoir landslide is different from other mountain landslides since its stability would be obviously influenced by the fluctuation of water level. The fluctuation of reservoir water level would change the hydraulic boundary conditions, which would lead to unstable seepage inside the slope. Traditional analysis method cannot study the deformational characteristics, the slope stability dynamic change and the unstable failure prediction of reservoir landslide. Based on the numerical limit analysis, the paper studies the deformational characteristics of landslide during the descending water level and the dynamic change of stability. The paper also quantitatively researches the deformational characteristics of landslide through the displacement-time relationship curve and displacement-logarithmic time relationship curve. Then, the paper puts forward taking the tangent angle in the acceleration section of displacement-logarithmic time curve as the criteria of sliding prediction, which provides a new idea to the understanding of failure mechanism of reservoir landslide and the improving of prediction.
