摘要
针对目前旧桥承载能力评定方法存在的不足,克服需大量借助昂贵荷载试验进行旧桥承载能力鉴定的缺点,主要介绍了混凝土旧桥表观损伤、强度、钢筋锈蚀电位、氯离子含量、钢筋分布及保护层厚度、混凝土碳化深度、电阻率、内部缺陷和表层损伤等的检测方法与评价指标及结构或构件的耐久性综合评定方法。
For the sake of conquering the shortage of existing bearing capacity assessment method for highway bridge in use and cut down the cost of loading test,The dissertation have studied a set of integrated and applied bearing capacity assessment method for highway bridge in use.The method is based on the existing condition and quality detect method of the bridge.It need to connect the simplex and isolated detection content with the ultima result,and make it quantified..The dissertation instroduces the test metho...
