  • To study the effects of surface deformation on hydraulic structure due to coal mining subsidence, an experiment system for soil hydraulic structure interface was developed to investigate the interface behavior under water.A series of soil-structure shear tests using the orthogonal experiment method were performed by that system.The influence of initial porosity ratio, initial saturation and surface roughness on mechanical behavior of soil-hydraulic structure interface.The test results showed that the system of the interface could study well the main mechanical behaviors of the interface under water and could realize the function of common direct shear apparatus.By means of range analysis and variance analysis, the results showed the initial porosity ratio designed had little impact on the shear strength.The initial saturation had a significant impact on the shear strength, which was affected by the method under water in saturated condition.Surface roughness had an impact on the shear strength, but more research was needed to study the influence rule.
