| Abstract: | According to the stress levels of the main girder and main tower of Tongminghai Crossing-sea Bridge,the coupling tests of environment and load have been carried out on typical members with different stress levels.The deterioration law of concrete structure durability under the coupling effect of environment and load has been studied.The influence mechanism of load on chloride ion diffusion of concrete has been analyzed and the influence law of load on chloride diffusion coefficient has been proposed. |

| Keywords: | concrete structure seawater environment coupling effect law of deterioration |
