The mechanical properties and durability of marine wharf concrete members constructed in 1997 in the east of China after 11years’service was widely surveyed and researched. The results show as follows: Compressive strength of members and concrete cover of members can meet the design demand but member’s resistivity is small; There is correlation between free chloride concentration and total chloride ions concentration and free chloride’s diffusion coefficient is smaller than total chloride ions; Surface chloride ions concentration reduces as elevation increases; The quality and corrosion resistance to chloride salt of members is different. The surveying results may make for establishing marine concrete standard.
