［摘要］鉴于板钢筋保护层厚度不满足验收标准的情况非常普遍，通过研究保护层厚度偏差现状，分析了除施工环节外，其他影响保护层厚度质量控制的因素，指出过于严格的验收标准和较大的施工难度是导致保护层厚度偏差的主要原因，提出在保证施工质量控制水平的前提下，应适度放宽验收标准、降低施工难度，并给出了调整验收标准和优化设计方案的具体建议，可为解决实际问题提供技术参考。

Abstract: It is very common that the thickness of reinforcement cover of slab does not meet the acceptance standard. By studying the current situation of the thickness deviation of the reinforcement cover, factors affecting the quality control of the thickness of the reinforcement cover were analyzed except the construction. It is pointed out that the main reasons for the thickness deviation of the reinforcement cover are too strict acceptance standards and great construction difficulty, and the acceptance standards should be relaxed appropriately to reduce the construction difficulty under the premise of ensuring the construction quality control level, and specific suggestions were provided for adjusting the acceptance criteria and optimizing the design plan, which can provide technical reference for solving practical problems. 

Keywords:slab； thickness of reinforcement cover； deviation of reinforcement cover thickness； acceptance standard； construction difficulty
