| 摘 要： | 为了研究降雨对边坡渗流场孔隙水压力分布的影响,根据岩土饱和-非饱和渗流理论,利用SEEP渗流有限元程序计算给定降雨条件下孔隙水压力的分布,结合一个土坡算例,探求降雨强度、降雨持时以及土壤渗透系数等参数变化对渗流场的影响。通过记录坡肩处孔隙水压力变化,得到不同降雨类型下雨水入渗深度的规律;并记录下坡体内孔隙水压力随时间的变化规律,得到持续降雨条件下不同时刻坡体内孔隙水压力分布特点,可以为边坡的稳定性分析和滑坡预测提供依据。

| Abstract: | In order to study the influence of slope seepage field's pore-pressure distribution under the conditions of rainfall,according to the saturated-unsaturated seepage theory,calculate the pore-pressure distribution is calculated under the conditions of a given rainfall using seepage FEM calculation procedures.With an example of a slope,parameters change is studied on the impact of seepage field,such as rainfall intensity,rainfall duration, soil permeability coefficient and so on.By documenting the slope shoulder pore-pressure changes,the depth of the seepage is gotten under the different types of rainfall;By documenting the pore-pressure with the changes of time,the slope seepage field's pore-pressure distribution is obtained in different time under the conditions of sustained rainfall,providing the basis of measurement for slope stability analysis and pre-landslide. |
