银川至西安铁路客运专线速度目标值研究

银川至西安铁路客运专线主要承担宁夏、蒙西及沿线地区与陕西及中东部地区间的快捷客运任务,两端兼顾城际客流的出行需求,速度目标值的选择尤为重要。为确定合理的速度目标值,综合考虑本项目的功能定位、时间目标值、沿线客流水平、投资效益,结合相邻路网协调性、经济社会发展协调性等多方面因素,采用250 km/h预留350 km/h速度目标值方案,可较好地适应近、远期客运需求,与经济社会的发展水平协调较好,与区域路网相协调,工程规模及投资水平适中,综合效益较优。

Research on Target Speed of Yinchuan-Xian Dedicated Passenger Railway Line

The Yinchuan-Xi'an dedicated passenger railway line undertakes the fast passenger-transport from Ningxia and west Inner Mongolia to Shaanxi and the areas in the middle-east of China,and also bears the intercity traffic at both ends of the line. The choice of target speed value is of great significance. The determination of reasonable target speed depends on such factors as transport volume,target timing value,passenger flow and the benefit of the investment,combining with the coordination of the railway networks nearby and the social and economic development. The target speed of 250 with reservation for 350 km / h is selected to meet the needs of the passenger flow in both short and long terms,to boost the social and economic development and to coordinate with local networks. The engineering scale and investment level are moderate and the comprehensive benefit is excellent.
