Bankside Stability Analysis under the Actions of Rainfall and Reservoir Water Level Fluctuation

Abstract:

It has been accepted that the rainfall and the reservoir water level fluctuation plays an important role in the stability of the reservoir bankside. However, at present, there has not been suitable simplification method for the project application to calculate and appraise. Therefore, based on the Boussinesq’s differential equation of unsteady-seepage and boundary condition, and Laplace’s transform, the curvilinear equation of phreatic line in landslide mass is deduced under the rainfall and the reservoir water level fluctuation conditions, and a simplified formula which can be used in the project is gained by the polynomial fitting. Meanwhile, it holds together the transmission coefficient method to write programs about the bankside stability analysis in the paper. With the Er-Liban landslide of the three Gorges Reservoir area for the computation model, this paper use the program to analyze the change rule and stability of the phreatic line under the reservoir water level fluctuation and rainfall condition.
