| Abstract: | Firstly, the paper introduces engineering geological condition and process of sliding of clayey gentle slope of Huangshan in Zhengjiang. Secondly, deformation and sliding mechanism of the landslide are analyzed. Furthermore, numerical simulation by means of finite difference method and strength reduction technique is implemented; and the result corresponds exactly to the field properties of the landslide. The clayey gentle slope stability is also analyzed considering variation of water level. The result indicates that usage of waterdrainage measure can improve notably stability of the slope. |
