关于点支承无砟轨道的探讨

Discussion on Point-supported Ballastless Track

本文在参考遂渝线嘉陵江大桥砂浆换填方案进行研究的基础上,参照砂浆换填支承结构形式,对点支承板式无砟轨道结构进行了垂向荷载作用受力分析,与其他无砟轨道结构进行了施工和维修方面的对比。通过分析可知,采用点支承式无砟轨道具有较优级的施工便利性和易维修性。

On the basis of referring to the research on the mortar replacement program of Suiyu Line Jialing River Bridge,this article referred the mortar replacement bearing structure,and conducted the vertical load stress analysis of point-supported slab ballastless track structure and compared the construction and maintenance with other ballastless track structure.Through analysis we can see,the use of point-supported ballastless track has a better level of construction convenience and ease of maintenance.
