Prediction analysis of Bazimen landslide deformation based on ABAQUS fluid-structure coupling
Based on the geological data of Bazimen landslide in the Three Gorges Reservoir Area,a two-dimensional model is established by using finite element software Abaqus.The inbuilt Monr-Coulomb model was used to deal with the elastoplastic deformation problem.The water pressure load,pore pressure boundary condition and rainfall load were set by the software user subroutine,and the fluid-structure coupling was analyzed.The process of landslide deformation and failure is numerically simulated from the aspects of seepage field,stress field,displacement field,plastic zone,etc.,and the predicted condition under the combined action of rapid periodic scheduling of reservoir water level and regional heavy rainfall is selected as the numerical analysis condition of landslide deformation trend prediction,and reasonable prediction and evaluation of landslide stability is made,and at the same time,it can provide reference for similar landslide prediction and early warning.
