The Slope Stability Analysis Under the Coupling Effect of Earthquake and Rainfall

摘要：

　　The rainfall and earthquake are two main causes of instability and failure of slope.To analyze the excess pore water pressure,the safety coefficient of slope and slope feature point displacement change with the time under the different earthquake intensity.The numerical modeling results of slope under the action of earthquake is inputted to the finite element analysis software,to the analysis dynamic change rule of volume moisture content and the formation of pore water pressure of slope soil mass under the condition of rainfall.Using the limit equilibrium method calculates and comparative analysis the slope stability after Coupling of earthquake and rainfall infiltration,and under the action of alone that earthquake or rainfall alone.The result shows that the earthquake makes slope geotechnical body to produce permanent deformation and increase the permeability coefficient of slope.Moreover,the rainfall infiltration will further decrease shear strength of slope,lead to the emergence of landslide.The earthquake combines with rainfall is more easily to induce landslide than single factor.
