Analysis on the Impact of Expansive Soil Slope Stability by Rainfall Infiltration
Expansive soil soften by water, leading to reduce soil strength, rainfall infiltration impact on the stability of expansive soil slope. In this paper, based on soil saturated - unsaturated seepage theory, by analysis on rainfall infiltration model used finite element analysis software, the model of expansive soil slope saturated - unsaturated rainfall infiltration was established to simulate groundwater rate and pressure head variation during rainfall the influence of slope seepage field and stability by rainfall infiltration was analyzed. Conclusion is that expansive soil slope under rainfall infiltration affects only occurs in shallow areas, low permeability affects slope effect of rainwater infiltration, fissured infiltration slope is slightly faster, short-term rainfall does not lead to a large area of the slope slumping damage, slope slip surface only in the surface layer, the performance of shallow slip. The theoretical basis and data reference are provided for expansion soil slope construction and protection.
