Numerical Simulation of Shear Characteristics of Reef Limestone-Concrete Interface
Reef limestone is the foundation of marine geotechnical engineering. It is very important to understand the mechanism of interface failure between reef limestone, a special porous medium of geotechnical engineering material, and concrete in actual projects, and in this study, the Finite-Discrete Element Method (FDEM) is employed to investigate this interface properties. Through large-scale shear tests, the shear force-shear displacement curves and shear failure characteristics of the reef limestone-concrete interface were obtained under two conditions of interface cemented or not. Based on the FDEM, a reef limestone-concrete interface shear model was established, and the feasibility of FDEM simulation analysis was verified by comparing the numerical simulation results with indoor experimental results. With the help of FDEM numerical simulation results, such as model perspective and local enlarged images, it was found that the location of shear failure may occur not only at the interface but also inside the reef limestone, which is a huge hidden danger for engineering practice and requires special attention.
