| 摘 要： | 挡肩裂纹是双块式轨枕预制的一项严重质量问题，将直接导致轨枕报废，若控制不到位，将给企业造成严重经济损失。以新建贵阳至广州铁路广宁轨枕预制场双块式轨枕施工为例，从脱模机构、混凝土配合比、混凝土养护等方面分析了挡肩裂纹出现的原因，并制定出针对性措施，为以后双块式轨枕的质量控制提供参考和借鉴。

| Abstract: | Based on the rail corrugation wear and tear occurring in China＇s high speed railway, this article makes a detailed introduction to the characteristics of rail corrugation, presenting the limitations of the current corrugation theory. The article also analyses the dynamic causes of corrugation in high speed situations, and the influence of tile railr＇s material on corrugation. Suggestions on preventing and reducing corrugation wear and tear are also provided. |
