摘　　要：通过缺陷普查,确定典型检测位置;以公路水运桥梁与隧道工程混凝土中氯离子含量取样方法为依据,结合相关规范氯离子含量测定方法;测定了某菜场海产品销售区楼板各深度层氯离子含量;检测结果表明,所测氯离子含量均未超过规范限值要求;通过穿孔验证,解释了板面深度层氯离子含量偏高的原因;通过电化学测试法与剔凿验证法结合的方式确定了钢筋锈蚀情况;并为结构后续使用及缺陷处理提出相应建议。The typical detection location is determined by defect survey;combined with the concrete Cl^(-) content sampling method in bridge and tunnel engineering and the relevant standard of Cl^(-) content determination method,the content of Cl^(-) in different depths of first floor in seafood selling area of a vegetable market was determined.The test results showed that the Cl- content-did not exceed the standard-limit.The reason of the high content of Cl^(-) in the deep layer of the plate is explained through the perforation verification.The corrosion of steel bar was determined by electrochemical test method and chisel verification method.Some suggestions are put forward for the structure subsequent used and defect treatment means.
