【 摘 要 】

The experimental study on the energy relationship between the coarse sand with different water content and the concrete interface with different hardness and roughness is carried out, through the high stress direct shear apparatus. Experimental results show that the growth rate of shear energy dissipation of sand-structure contact surface is slowing down with the increase of roughness, even negative; The shear energy dissipation of concrete with different hardness decreases first and then increases with the increase of water content, The crushing energy consumption is the lowest when water content is 16%; The shear energy dissipation at different moisture content increases with the increase of the contact strength of concrete structure.
