列车速度目标值的选择是短距离城际轨道交通工程制定技术标准的重要依据,通过结合全线车站分布情况,定量计算采用80、100、120 km/h速度目标值的节时效果,并分析采用3种速度目标值的技术可行性,以及对土建工程、机电工程投资的影响,综合比较分析,最终确定出经济、合理的速度目标值。
The selection of train speed target value is an important basis for setting technical standards for short-distance inter-city rail transit project. By combining the distribution of all stations, the time-saving effect of using 80,100,120 km / h speed target value is quantitatively calculated and analyzed The technical feasibility of the three kinds of speed targets, as well as the impact on civil engineering, mechanical and electrical engineering investment, a comprehensive comparative analysis, and ultimately determine the economic and reasonable speed target.
