Mathematical Model for Shear Stress-strain Relationship of Soil-concrete Interface during Shear Fracture Process

摘要

Description of shear stress-strain relationship for soil-concrete interface during shear fracture process plays an important role in experimental and numerical studies of soil-structure interaction. In this paper, deficiency of traditional hyperbolic model for the shear stress-strain relationship is analyzed, firstly. Then, a new model with 3 parameters for it is established, which can overcome the deficiency of hyperbolic model. Finally, good agreements have been found between the proposed model and laboratory tests.
