Description
Summary:Although a lot of researches about temperature-stress and crack of mass concrete have been published, there are still many work on crack control to be improved. At present, due to the development of a general chemo-thermos coupled model for hydration of concrete, multi-field coupled method has been a hot topic in the field of studying the evolution of concrete properties. Therefore, in this paper, a chemo-thermos- mechanical coupled model of concrete hydration is developed and applied to the finite element analysis. Through this method, the temperature-stress of concrete gravity dam encountering cold wave are studied. The settlement results show that this method is more consistent with engineering practice than traditional methods, and can provide reference for construction and design.
