堆积体滑坡抗滑桩所受推力计算及分布特征研究
Distribution laws of thrust of talus slide on anti-sliding piles
摘要
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.关键词
