在河水位骤降条件下某滑坡浸润线计算与滑坡稳定性研究

landslide in the right bank of a river was investigated. Conditions of the landslide occurrence were analyzed. The main factors of influence on the landslide groundwater saturation line and landslide stability were discusses. A mechanism of the landslide formation was revealed. A model and a method for calculating the landslide groundwater saturation line and landslide stability were given. The most unfavorable conditions were considered. The landslide groundwater saturation line graph was calculated and drawn under the conditions of the river water level drop. The landslide stability coefficients and the rest slipping force of the sliding mass under different conditions were calculated. The river water level fluctuation influences slope groundwater saturation line and changes the unsaturated zone of rock and soil so as to influences shear strength of weak layer of rock and soil and stability of a landslide. Seepage force accelerates the landslide deformation under the condition of river water level drawdown. Research achievements can provide the landslide control and engineering design with a reliable basis and have important significance.
