| Abstract: | Based on the testing results of concrete for marine pile pier,it is deemed that chloride ion,quality of concrete,thickness of protective layer,crack of beans and slabs by applied load are the factors influencing durability of concrete.It is advanced that improving quality of concrete,using prefabricated elements,controlling the width of crack in design,using fiber reinforced concrete,arranging two layers of force steel bars in the precast concrete slab of precast and cast insite concrete slabs are the fundamental method to solve the problem. |
