Law of groundwater movement of slope under rainfall condition

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.
