摘要
针对衔接无砟轨道的安全线轨道类型的选择,分析设计中存在的差异及其原因,分别从钢轨类型的选择、道床类型的选择和安全线上护轮轨的设置等方面研究选择方案,并且分析无缝线路对安全线有效长度的影响。针对站线及道岔钢轨材质的选择,分析设计中存在的问题及其原因,根据常见钢轨材质,分别提出站线和道岔的钢轨材质选择方案。
Targeting with track type selection of the safety siding connected with ballastless track, this paper analyzes the difference existing in the design and its reasons, studies the Selection programs from aspects of selection of rail type, selection of track bed and the setting of guard rail on safety siding respectively, and analyzes the influence of ballastless track on the effective length of safety siding. Targeting with the rail material selection of side track and turnout, the paper analyzes problems existing in the design and its reasons, and according to the material of common rail, puts forward the programs of rail material selection of side track and turnout respectively.
