摘要
在采用土体孔隙水压力描述非饱和土渗透特性的基础上,对某土坝模型进行了饱和—非饱和渗流计算,并应用于降雨入渗条件下的边坡稳定分析.计算成果表明,对于地下水位较深或可能出现浅层滑坡的情况,采用非饱和土强度理论得出的计算成果更为符合工程实际.
Based on stating the seepage feather of non-saturated soil by adopting the neutral pressure of soil, the saturated flow calculation and non-saturated flow calculation of a certain earth dam model were made and it was opplied to analyze the slope stability under rainfall infiltration. The results shows that the calculation results of adopting the strength theory of the non-saturated soil tally with the actual situation of projects in the condition of deeper underground water level or probale shallow landslide.
