| Abstract: |
In order to study the effect of environmental variables on the chloride concentration on the concrete surface under the action of drying and wetting cycles. Firstly, the influence of environmental variables such as monthly average temperature, monthly sunshine duration, and monthly rainfall on the dry-wet time ratio in Haikou and Wenchang was analyzed, and the dry-wet cycle mechanism of the Puqian Bridge was established. Then, according to the dry-wetting cycle mechanism, the influence of multiple factors on the distribution of chloride concentration on the surface was discussed, and a model of the chloride concentration distribution on the surface of unsaturated concrete under the action of multiple factors was established. Finally, the distribution model is compared with the experimental data in the literature to verify the rationality of the distribution model. |
