The main factors of rock-concrete interface shear strength deterioration were reviewed, including chemical erosion, temperature effect and load impact. The existing macro and micro test methods of rock-concrete interface were summarized. The degradation models of interface shear strength considering the mechanical properties of rock and concrete, the characteristics of interface roughness, the initial cohesion of interface, and normal external stress were summarized. Given the rock-concrete interface in hydraulic engineering is prone to corrosion degradation under high hydraulic gradients, problems including the shear strength degradation mechanism, shear strength degradation model, and interface crack propagation are proposed to be further studied. Keywords: permeable corrosion; rock-concrete interface; shear strength; deterioration model 〖FL
