摘　　要：为能更全面准确地掌握桥梁的耐久性状况,对桥梁主要承重构件的现状做出综合评定和桥梁检算、荷载试验提供进一步可靠数据。在桥梁常规检测的基础上,采用一些专门技术和检测设备,对一些重点部位的钢筋锈蚀、混凝土碳化、保护层厚度以及构件质强进行特殊检测。通过对室内试验与室外检测的实验数据进行分析。结果表明:这些特殊检测内容对结构耐久性都有着一定的影响,而且这些影响因素之间也存在互相影响关系。Based on the bridge routine examination,the steel corrosion,concrete carbonation,the thickness of the protective layer and component quality of the key parts of bridge were detected using the expertise technology and testing equipments.This may provide technical data for the next bridge inspection count and load test.The indoor experiment and outdoor test results show that：the special inspection contents have certain effects the structure durability,and those influencing factors also affect each other.
