摘要
速度目标值是城际铁路设计时的核心指标,在选取时主要以适应客流需求、与区域其他交通运输方式相协调、与沿线社会经济发展相适应为原则,体现有利于吸引客流、减少工程投资和运营成本的效益最大化原则。速度目标值的选择主要通过本线客流特点、时间目标值的选择和具体多个速度目标值的比选得出。文中以长沙—益阳—常德速度目标值的选择为例,阐述铁路设计中客运专线速度目标值的选择方式和方法。
Choice of Speed Target Value is the core index of intercity railway design.It is chosen primarily to meet the passenger demand,and regional coordination of other transportation modes,and adapt to social and economic development along the principle,reflect the will attract passenger traffic,reduce engineering investment to maximize the benefits.Target value is decided by the passenger flow characteristics,time target selection and specific multiple speed target value.Taking the choice of speed target value of intercity railway from Changsha to Changde as an example,this paper expounded the speed target value selection modes and methods in the railway design.
