A "Thermal-Micromechanics" coupling approach for corrosion and crack of anchor in the corrosive environment is researched in this study. The thermal module of software PFC2D is applied to simulate diffusion of corrosive media in the concrete while the mechanics module of PFC2D is applied to model stress corrosion and crack resulting from long term tension stress. Information related to the concentration of corrosive media is transferred into the mechanics module to modify the initial crack stress. Bond-fracture information is then read by the thermal module to change the concentration in the crack position. Comparison with experimental data indicates this coupling approach may model diffusion of the corrosive media and the crack satisfactorily.
