Numerical Simulation and Failure Mechanism of Landslide Stability under Different Rainfall Conditions
Through on-site investigation,application of improved Mein Larson rainfall infiltration model,numerical simulation and theoretical analysis,the stability and formation mechanism of rainfall induced loess landslides were analyzed.The research results showed that with the increase of rainfall intensity and duration,a transient saturation zone is formed at the foot of the slope,leading to changes in the stress field and displacement range of the slope,and a decrease in the shear strength of the surface soil.It is inferred that the landslide is a creep tensile crack type landslide.
