【 摘 要 】

The salt spray gathering in the grillage space of piled beam-slab wharf could easily make the beams corroded in the harsh marine environment, which would cause an adverse impact on the durability of structure. The three dimension model of grillage space of piled beam-slab wharf was established by the fluid dynamic module CFD of ANSYS. Based on the results the vent setting was optimized, the result showed that the vent setting in the longitudinal beam could improve air flow distribution of grillage space effectively. As the distance between the vent and two ends of beam was about one meter, the dissipation effects for salt spray was most significant.
