【摘要】 钢筋保护层厚度直接影响结构构件的耐久性、承载力。只有在保证施工质量的前提下，混凝土才能对钢筋提供可靠的握裹力，两者才能更好地协同工作。文章介绍了目前钢筋保护层厚度的常用检测方法、检测原理以及影响检测结果的因素；归纳总结出8条提高钢筋保护层厚度检测准确度的方式方法；结合案例分析，给出了墙、柱类构件混凝土保护层厚度检测的方法、步骤和评定方法。钢筋保护层厚度施工质量不易控制，对结构构件钢筋保护层厚度的精准检测和合理评定具有非常重要的意义，相关标准也宜尽快完善验收要求。更多还原

【Abstract】 The thickness of steel bar protective layer directly affects the durability and bearing capacity of structural members.Only under the premise of ensuring the construction quality, the concrete can provide a good bonding force to the steel bar, and the two can work better together.This paper introduces the common detection methods, detection principles and factors affecting the detection results of the thickness of the protective layer of steel bars.8 ways is summarized to improve the detection accuracy of the thickness of the steel cover.Combined with case analysis, the method, steps and evaluation method of concrete cover thickness detection of wall and column members are given.The construction quality of the thickness of the steel bar protective layer is not easy to control.It is of great significance to accurately detect and reasonably evaluate the thickness of the steel bar protective layer of the structural members.The relevant standards should also improve the acceptance requirements as soon as possible.更多还原
