中文摘要：
基于对乍浦港混凝土结构现场检测数据,分析干湿交替区域氯离子侵蚀状况存在差异的原因,建立表面氯离子浓度和扩散系数随高程、季节、材料、及服役时间的关系,提出基于海域气象条件推定扩散模型统计参数的经验计算公式,并根据设计潮位确定氯离子严重侵蚀区域范围,可为耐久性设计和维护提供理论依据。
英文摘要：
Based on the field data of RC structures at Zhapu port,the difference of chloride level in wet-dry cycling zone is analyzed.Surface chloride level and apparent diffusion coefficient are related to the altitude,season,material and service time of RC structures.An empirical method is developed to determine the diffusion model parameters according to the meteorological information of sea area,and also the range of hot spot if design tidal level is known.It contributes to durability design and maintenance of harbor concrete structure.
