后置式海工结构钢筋腐蚀监测系统设计及在跨海桥梁上的应用

DESIGN OF POST-MOUNTED OFFSHORE STRUCTURAL STEEL CORROSION MONITORING SYSTEM AND ITS APPLICATION ON CROSS-SEA BRIDGES

为全面反映海工钢筋混凝土结构安全状况,在研究海工混凝土结构钢筋腐蚀机理及现有监测技术的基础上,针对多样的监测参数,设计了一种后置式海工结构钢筋腐蚀监测系统,通过在大连某跨海大桥上的测试应用,表明该系统设计方案合理,监测结果符合预期,能够满足海工结构钢筋锈蚀及混凝土腐蚀的在线实时监测与预警的需求,有利于工程技术人员对海工基础设施的安全性和耐久性做出更科学的评定。

In order to comprehensively reflect the safety condition of the offshore reinforced concrete structure,a post-mounted offshore structural reinforcement corrosion monitoring system was designed based on the study of the corrosion mechanism of offshore concrete structural reinforcement and the existing monitoring technology,and for diversified monitoring parameters.Through the test application on the Bridge in Dalian,it shows that the system design is reasonable and the monitoring results meet the expectation,which can meet the demand for online real-time monitoring and early warning of reinforcement corrosion and concrete corrosion of offshore structures,and is conducive to the engineers to make a more scientific assessment of the safety and durability of offshore infrastructure.
