Stability Analysis of Weathered Mixed Granite Slope under Strong Rainfall
In the construction of expressway in southwest China,there are many weathered granites.While the study of weathered migmatite is very little at present.To ensure the safety of slope,the study of the mechanical mechanism of rain-induced stability of weathered migmatite slope has been carried out.Based on the actual slope engineering,PLAXIS finite element analysis software was used,the slope finite element model was established,the changes of slope stability is analyzed under different rainfall patterns and different permeability coefficients.The research shows that when the rainfall is constant,the rainfall in different periods has a greater impact on the slope stability.The greater the permeability coefficient,the more the slope stability will decline.
