Abstract: Talus always slides along the bedrock surface. On the basis of straight shear tests on earth-rock aggregate and bedrock, the sliding surface of talus slide is a combination of two media strain-hardening and strain-softening. A shear stress-strain constitutive model for the strain-softening medium is described by the Weibull’s distribution law. A shear stress-strain constitutive model for the strain-hardening medium is described by the linear equation. Based on a simplified model for anti-sliding piles in talus slide, the formulas for calculating thrust on anti-sliding piles are derived by considering the above two shear stress-strain constitutive models. How the main parameters of the proposed formulas affect the distribution laws of talus slide thrust on anti-sliding pile is discussed. Finally, the rationality of the proposed formulas is demonstrated based on comparative analysis of the theoretical and the experimental results.
