摘要
针对处于海洋与化冰盐环境中的工程因氯盐引起钢筋锈蚀大幅度降低普通钢筋混凝土结构使用寿命的主要问题 ,综述了有关防锈技术措施、结构寿命与高耐久混凝土技术要求 ,并介绍了近 5年内建成的 4座设计使用寿命为 10 0～ 12
To counter the main problems that chloride induced reinforcement corrosion substantially decreases the lifetime of conventional concrete structures of engineering in hostile marine and deicing salt environment, the methods for corrosion prevention, definition of lifetime, technical requirements for high durable concrete and concrete specifications for 4 marine bridges, completed in last 5 years, with design lifetime of 100～120 years have been reviewed.
