| 摘 要： | 讨论了考虑非饱和流渗作用下的土坡的数值计算分析,采用了不同含水量对抗剪强度影响的模型,求解带有渗透力作用项的土体弹塑性平衡方程得到土坡的应力应变分布,并应用于降雨滑坡的简单算例分析。由算例分析得知,利用非饱和渗流耦合应力的弹塑性来分析非饱和渗流而引起的土体滑坡的变形和发展是可行的,并值得完善和发展。

| Abstract: | The present paper discusses the numerical analysis of soil slope under unsaturated seepage action. The model of shear strength with different water contents is adopted. The stress and stain of soil slope are determined by solving the coupling elasto-plastic equilibrium equations with seepage force taken into account, and the analysis method is applied to the computational example of slope caused by rainfall in the paper. The example is given and conclusion has been drawn. It is feasible and beneficial to use the numerical method to analyze slope deformation under unsaturated seepage. Besides, the method needs to be improved and developed in the future. |
