摘　　要：介绍了500 m长钢轨铺设施工后预留轨缝发生变化的情况,分析了预留轨缝的分析和计算方法。该方法可避免低温条件下引起的钢轨收缩不超过构造轨缝,高温条件下预留轨缝的两头钢轨不严顶,有效通过预留轨缝,减少后期养护工作和确保安全行车。This pape introduces the 500 m long steel rail laying construction after the pre-set rail joints change,analysis of the pre-set rail joints analysis and calculation method.The method can avoid the low temperature conditions caused by the rail shrinkage does not exceed the construction rail joints,high temperature conditions reserved rail joints of the two ends of the rail is not strict top,effective through the reserved rail joints,reduce the late maintenance work and ensure safe traffic.

关 键 词：铺设500 m长钢轨 预留轨缝 计算方法
