| Abstract: | Calculations of unsaturated seepage field of Dayantang slope during the heavy rain season, have been made. In the calculation, the drainage is taken into account. The stability analysis using elasto_viscoplastic finite element method is then carried out considering the effect of the unsaturated seepage. The results show that the rainfall is the main factor influencing the deformation and the stability of this landslide, and the stability of the slope may be improved if the underground water is lowered effectively by the drainage system. |
