摘　　要：用钢筋腐蚀检测中常用的表层混凝土电阻率检定法,对自然暴露7年的组合构件中的栓钉腐蚀进行了检测研究,对比破损检查结果发现,表层混凝土电阻率法不适于组合结构中栓钉腐蚀的检测和腐蚀状态判定。Surface concrete resistivity method which is usually used to map the rebar corrosion is employed to detect the corrosion of studs in steel-concrete composite structures.After comparing with the destructive testresults ,it is concluded that the surface concrete resis-tivity method is not suitable to judge the corrosion state of studs in the composite structures.

关 键 词：组合结构 栓钉 腐蚀 电阻率
