摘要
A self-developed large shearing equipment was used for shear tests on two contact interfaces in situ: concrete-sandstone and concrete-siltstone,to study the characteristics of their shear deformation and shear strength.The results reveal the relationship between stress change and displacement,as well as that between contact surface destruction modes and shear strength.
