摘要:

依托舟山嵊泗县李柱山西侧客运码头工程，将高性能混凝土应用于部分码头结构，分析码头涂敷防腐涂料隔绝码头受海洋环境的影响。通过分析这两项措施对改善码头耐久性能的有效性和经济性，提出改善混凝土码头耐久性能的建议。研究认为，就原材料成本而言，高性能混凝土价格略微低于原普通混凝土，氯离子迁移系数仅为约原普通混凝土的一半，防腐涂料的采用将增加码头建设成本。建议防腐涂料仅在结构中重要的部位或容易受腐蚀的部位采用，而不必整个码头采用。

Abstract:

The durability of Lizhushan Port in Shengsi County, Zhejiang Province was studied. High performance concrete (HC) was partly applied in the port with protective paint was coated on it. The chloride diffusion coefficient of both HC and original concrete (OC) was tested and compared. The cost of the application of HC and the protective paint was calculated. The results show that the application of HC could reduce the cost slightly, and the chloride diffusion coefficient of HC was smaller than that of OC. The coating of protective paint could increase the cost significantly. A suggestion was made that the protective paint may be coated on key parts of the port.
