To explore chloride ion erosion in the crack propagation process of concrete structures under loads, and more accurately describe the characteristics of chloride ion erosion around cracks at different stages, the development process of concrete trabeculae type Ⅰ fracture, based on the concrete fracture criteria, was simulated by self-programming, and redeveloped by ANSYS parametric design language APDL. Given the mapping relationship between volume strain, damage variable and chloride ion diffusion coefficient, the parameter equivalence method and the structure-thermal analysis method are used for numerical analysis of chloride ion erosion at various stages of concrete crack propagation. The results show that chloride ion erosion around the crack of a three-point bending concrete trabecular is consistent with the experimental one at different crack-expanding stages. The chloride ion erosion at the crack tip of concrete is intensified under loads; therefore, it plays a decisive role in the durability life analysis of concrete structures. Furthermore, the double-
