【摘要】 本文采用超声回弹综合法检测了某大桥桥面钢筋混凝土板的强度,并对混凝土结构耐久性的重要物理力学性能指标———碳化深度、钢筋锈蚀等进行了同步检测,结果表明该桥虽经40余年的使用,除少数几块板需要加固补强外,其余板的质量基本符合原设计要求。更多还原

【Abstract】 In this paper,strength of reinforced concrete slab has been tested with Synthetic Method of Ultrasonic and Rebound in the road surface structure of first bridge of Xiang Tan.And the important physical and mechanical performance of the durability of concrete structure has been tested too.such as depth of carbonization and Corrosion of reinforced bars etc.The results showed that this bridge has been used for more than 40 years,except a few slab require to be strengthened,the quality of other slab is in accordance with the original designing requirement.更多还原
