1、摘要铁路是现代文明的一项巨大工业成就,在国民经济的发展过程中发挥着不可或缺的作用,因此在本次铁路选线设计当中,充分结合当地地形的实际条件,力求作到行车安全平顺、节约资金、布置合理、线形美观。本篇为Ⅲ级铁路东南村—九龙江段选线设计。此地区地形属于山岭重丘,路段全长4630m。设计内容主要是依据《铁路线路设计规范》、《铁路选线设计》和《轨道结构》等文献进行平面线形设计、纵断面设计、横断面设计、边坡稳定性验算、挡土墙设计以及轨道结构设计。平面线形设计主要是利用纬地软件进行纸上定线、平曲线要素确定;纵断面设计包括地面高程、
2、设计高程、坡段设计和竖曲线要素;横断面设计是根据地质条件及《铁路路基支档物设计规范》,绘制出每桩横断面,同时对路基边坡稳定性分析,确定临界高度,加上挡土墙。本文对轨道结构的钢轨、轨枕、道床以及曲线轨道的超高、加宽分别进行了设计,最后根据运营条件对轨道强度进行验算。本设计在制图方面严格按照中华人民共和国国家标准《道路工程制图标准》进行,采用纬地CAD制图,理正岩土对土坡和挡土墙进行验算。关键词:铁路选线设计纵断面横断面挡土墙边坡稳定性轨道结构ABSTRACTAsanimportantpattenofthetransp
