本文应用桥梁结构无破损检验技术,对钢筋的锈蚀、混凝土碳化、含氯率、电阻率等进行了测定。经试验、分析、评定认为,该桥除严重开裂,雨水浸蚀部位需要补强处理外,整个上、下部结构不仅可以满足现行交通要求,而且结构功能还可满足提高一个荷载等级,达到汽—20的标准,该桥的耐久性能较好。 In this paper, the bridge structure without damage test technology, the corrosion of steel, carbonation of concrete, chlorine content, resistivity were measured. The test, analysis, assessment that the bridge apart from serious cracking, rain erosion parts need to be reinforced treatment, the entire upper and lower structure not only to meet the current traffic requirements, but also to improve the structural function of a load level to achieve steam - 20 standard, the durability of the bridge is better.
