Abstract Because of special mechanical characteristics of expansive soil and disturbance of sliding，it is hard to obtain the soil shear strength parameters by general shear experiments in lab. Whereas，shear strength of soil is crucial in the stability analysis of landslide. The method of back calculation with multidimensional chart is given to calculate soil shear strength of landslide in expansive soils conveniently. The validity of the method is shown by computation examples.
