Infinite Slope Stability Under Transient Rainfall Infiltration Conditions

摘要

The infiltration process of infinite slopes was studied with modified Green-Ampt infiltration model. The process was divided into two stages, in which the depth of the wetting zone and underground water was calculated. Stability analysis considering different sliding patterns was conducted on the basis of seepage analysis. The safety factor of infinite slopes at different time stages has been derived. Equations in this paper could be used for predicting rain-induced landslides with limited parameters available.
