摘　　要：根据海港高桩码头结构检测结果,认为氯离子、混凝土质量均匀性和保护层厚度、构件受力产生的裂缝是影响混凝土耐久性的因素.提出提高混凝土的质量、优先采用预制构件、从设计上控制裂缝开展宽度和推行纤维混凝土等有效措施.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.
