摘要
基于既有白乌铁路160 km/h技术特征,分析提速200 km/h平面技术条件。对比200 km/h城际铁路、200 km/h客货共线铁路、160 km/h普速铁路在圆曲线和夹直线最小长度、圆曲线半径最小值及缓和曲线长度、线间距方面技术要求,分析160 km/h线路平面主要技术参数对开行200 km/h动车组的适应性。统筹考虑曲线半径、控制点情况、废弃工程等因素,初步提出有价值的提速段落,并针对可能的提速段落综合考虑线间距、运行组织、投资等因素研究不同方式的提速方案,最终推荐分阶段采用4.2m和4.4m线间距不同方案实现提速200 km/h的目的。
Based on the technical feature of 160 km/h design speed of existing Bai-Wu Railway,the plain technical condition for speed-raising 200 km/h was analyzed.Thereafter,this paper analyzed the adaptability of the main plain technical parameters of 160 km/h railway to running 200 km/h EMU by comparing the technical requirements of 200 km/h intercity railway,200 km/h mixed passenger and freight railway and 160 km/h normal speed railway in the aspects of the minimum length of circular curve and intermediate straight line,the minimum radius of circular curve,the length of transition curve and the distance between lines.Based on the overall consideration of curve radius,restriction points,abandoned projects and other factors,this paper initially put forward valuable speed-raising sections,and studied different speed-up schemes for possible speed-raising sections by comprehensively considering track spacing,operation organization,investment and other factors.Finally,it was recommended to adopt different schemes of 4.2 m and 4.4 m track spacing in stages to achieve the purpose of speed-raising 200 km/h.
