摘　　要：对比国内外对于钢筋最小保护层限值和允许偏差的发现,我国规范对于最小保护层限值规定偏小,允许偏差严格。轨道工程与建筑工程之间存在较大差异,轨道工程直接套用房建工程的验收规范,其合理性有待商榷。对钢筋保护层厚度控制的措施进行试验验证发现,采用钢制间隔件可以达到较好的效果,可以在轨道工程中推广使用。Compared with the minimum limits and allowable deviations of cover to reinforcement in domestic and overseas,the limit value of the minimum protect layer is relatively small and the allowable deviation is relatively strict in China’s acceptance codes.Considering the large differences between track engineering and construction engineering,the rationality of applying the acceptance codes of building engineering directly in track engineering is debatable.Through the test verification of the measures to control the thickness of the cover to reinforcement,the results show that the steel interval parts can achieve a better effect,which can be extended and used in track engineering.
