摘要
为满足较低设计速度的客运专线线路设计需要,补充完善现行标准体系中有关线间距加宽标准的规定,在分析借鉴现行有关标准或规定基础上,针对较低速度客运专线线间距加宽标准进行有关探索研究。线间距加宽值的确定与车辆性能、线路运营特点、设计速度等有关,不能简单地按照设计速度套用现行标准中某一取值。通过系统分析线间距加宽要求、影响因素、计算方法等,结合我国客运专线有砟轨道实设超高设计及养护规定,提出了低速客运专线亦或兼顾轻快货运的线路线间距加宽计算公式。对于线间距加宽值的设置,在满足现行有关强制性标准规定基础上,应结合建设项目特点,按照线间距加宽原理分析加宽需求,灵活运用计算理论,确定适宜的加宽标准,细化或优化工程设计,为实现工程设计的技术经济合理性奠定基础。
To serve the design of low-speed passenger-dedicated line,supplement and perfect the standard of widening the distance between centers of tracks in current standard system,this paper explores and researches into the standard of widening the distance between centers of tracks based on the analysis of current relevant standards and regulations.Because the widening values are related to vehicle performance,line's operating characteristic,design speed and so forth,it cannot be set mechanically by the current standards of the values which accord with the design speed.This paper,aiming at the distance between centers of tracks,through systematical analyses on the widening requirements,influence factors,calculation method and so on,combining with the superelevation design and maintenance regulations of China's passenger-dedicated line with ballast track,puts forward the calculation formula of the low-speed passenger-dedicated line or light freight line.When determining the widening value,the designer,based on the current relevant mandatory regulations in combination with construction project's characteristics,should analyze the widening requirement in accordance with the widening principle of the line,flexibly utilize the calculation theory to determine the appropriate standard of widening,detail or optimize the engineering design,so as to lay a foundation for realizing the rationality on technology and economy in engineering design.
