摘　　要：GB 50204—2015《混凝土结构工程施工质量验收规范》[1]规定涉及结构安全的有代表性的部位应进行结构实体检验,其中一项是钢筋保护层厚度。在对混凝土楼板保护层的实际检测中,存在实测值与设计值不一致的情况,将实测保护层厚度可判定为合格、实测保护层厚度不合格且大于上限要求、实测保护层厚度不合格且小于下限要求三种情况进行分析探讨。GB 50204-2015“Code for Acceptance of Constructional Quality of Concrete Structures”stipulate representative parts of structural safety should be examined by structural entities,one of which is the inspection of concrete cover.There is a discrepancy between the measured value and the design value in the actual detection of concrete floor protection;it can be divided into three kinds of situations to measure protective layer thickness,which were the measured values of concrete cover can be classified as qualified,the measured values of concrete cover can be classified as unqualified and greater than the upper limit,the measured values of concrete cover can be classified as unqualified and less than the lower limit.
