Abstract

To achieve the structural design of high-temperature molten salt tank foundation under multi field coupling, the distribution of temperature field and stress field and the sensitivity of the initial environmental temperature, convective heat transfer coefficient, and coefficient of thermal expansion of the molten salt tank foundation were analyzed by finite element analysis. The results show that the initial ambient temperature was inversely proportional to the stress of the steel ring plate. Diurnal temperature difference has little effect on foundation, while seasonal temperature difference has great effect on foundation. The stress of the steel ring plate under self-weight load is 3% of the stress of the steel ring plate under the action of temperature, so it is necessary to take insulation measures for the steel ring plate in the structural layout.
