Abstract
This papers mainly concerns on the mechanisms of shallow rainfall-induced landslides respect to hydrological processes related to either 1) increase of positive pore pressure or 2) loss of soil suction (negative pore pressure), and its effect on the subsequent reduction of shear resistance. The hydrological process of one-dimensional transient flow can be modeled by RichardâTMs equation, and the factor of slope stability is available that make use of soil-water retention characteristics and shear strength expressions. Parameter values attained form sandstone and mudstone are applied in DDA program to perform simulations of the slope failure under the influence of water content and corresponding pore-water pressure.
