摘要：
Shear behavior of interfaces between steel and soil composed of crushed sandstone and mudstone greatly influences the side resistance of RSCFST pile, a new kind of pile widely used in deep water wharf in western China. This paper presents the results of experimental studies on the shearing behavior of the soil-steel interfaces. Strain-controlled shearing tests are carried out with a direct shear apparatus under constant normal load condition. The influence of water content on the response of the interfaces is investigated. The test results reveal nonlinear relations between the shear strain and the shear stress. It indicates that the shear strength of the interfaces obey the Mohr-Coulomb criterion. The strength parameters, including cohesive force and friction angle are influenced greatly by the soil properties as well.
