Slope stability analysis by using multiple shear strength model

Slope stability analysis by using multiple shear strength model

Rainfall-induced landslide is a condition where rain water infiltrates into slope causing additional load and loss of shear strength of soil mass and eventually triggers slope failure. It is difficult to determine by applying conventional slope stability method as the method normally ignores the rol...
