【摘要】 介绍了混凝土中钢筋腐蚀机理与半电池电位法检测钢筋腐蚀状态的原理,结合日照港煤码头各泊位的检测数据,根据钢筋锈蚀的理论概率公式,通过试验与理论分析,验证了半电池电位法的可靠性,结果表明计算值与试验检测结论吻合较好。为提高海洋环境下混凝土构件的耐久性,建议严格限制氯离子的初始含量;运行管理阶段加强定期安全监测维护。更多还原

【Abstract】 We introduced the reinforcement corrosion mechanism in reinforced concrete and the principle of testing by half cell potential method.Based on each berths′ test data in Rizhao Port and theoretical probability formula of steel corrosion,we confirmed the reliability of half cell potential method by experiment and theoretical analysis.The results show that the calculated values are in good agreement with the test data.To improve the durability,it′ s necessary for concrete members in marine environment to limit the initial content of chloride ion.Besides,regular security monitoring and maintenance on operation management stages should be strengthened.更多还原
