    • Abstract
  • Wantang landslide is an earth landslide on the north bank of Xiangxi river located of in Zigui County of Hubei Province. The anti-slide pile planned to be taken for managing the slope is urgently in need to evaluation the effect of control. Following analyzing the characteristics of the landslide and the cause, we can combine the limit equilibrium method, FLAC3D explicit finite difference method, ABAQUS finite element method for analyzing the treatment effect from five aspects such as the variation of the stability coefficient, the residual thrust, stress-strain characteristics, the change in plastic zone and the force on the anti-slide pile before or after taking measures. The result shows that not only local stability is improved, but also the overall stability is in accordance with the specifications. It is helpful for analyzing the stability of landslides under natural conditions and provides a good reference for the evaluation of treatment effect of land-slide. It is also significant for monitoring arrangements after the construction.
