The basic hypothesis of residual thrust method is only suitable for perfect-plastic materials or strain-hardening materials. For the slope with strain softening properties

the applicability of this method will be limited. This paper based on the strain softening properties of soil aims to explore the relationship between shear strain and the shear capacity

by introducing equations of strain compatibility at the bottom of the bars

the method for landslide thrust calculation is improved; and then a new method for calculating designed thrust of anti-slide pile considering strain softening properties is proposed. The case studies show that the coefficient of landslide stability calculated by improved calculation method is between the values respectively computed on the condition of peak strength and residual strength; and the designed thrust of anti-slide pile obtained by improved method is much lower than that obtained by residual strength

but is higher than that obtained by peak strength

is between the two sides all the same. The method proposed is based on the current status of the landslide; so it can curb the further development of the landslide and also conform to the actual situation of the slope at present.
