Abstract:Seepage discharge and exit water level in permeable layer cannot be computed with traditional seepage model in translational landslides,and both are assumed invariable as the water level in the slope cracks changes,which influences the accuracy of computation results in the range of artesian water. A new seepage model of translational landslide was thus established. Based on one-dimensional seepage theory of underground river channel,a new method was proposed to compute the action range of artesian water,seepage discharge and water level in seepage exit. Based on the geological data of Xiashan landslide,the safety factor was computed with different models and the outputs were discussed. Finally,the intrinsic relations and sensibility analysis of relative parameters including geological parameters,dimensional parameters and initial parameters of hydraulic condition were studied. Results showed that the range of artesian water,the seepage discharge and the water level in seepage exit were influenced significantly by the water level in the cracks of slope. The safety factor of slopes based on the new model is more reasonable and accurate. Any change in the model?s parameters made a difference in the range of artesian water,unit discharge and water level in seepage exit.
