摘要
对大岩淌滑坡暴雨期的非饱和渗流场进行了计算 ,同时考虑了排水的作用 ,并应用弹粘塑性有限单元法对滑坡体在非饱和渗流场作用下的稳定性进行了分析评价 .结果表明 ,有效地降低滑坡体中的地下水位 ,可以明显地提高其整体稳定性 .
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.
