速度目标值是高速铁路主要技术标准之一，是铁路行车技术的核心指标，是总体设计的决定性参数，也是体现铁路系统整体技术水平的最主要指标。设计采用的速度目标值对线路的走向、长度、工程投资、运营费用、牵引质量及输送能力都有较大的影响。文章首先从京九通道及本线客流构成、旅客时间目标值的研究着手，从考虑本线城际客流同高速公路竞争，并尽量缩短长途客流旅行时间等因素出发，提出了本线的时间目标值；然后对3种速度目标值情况下的技术及工程投资的差异作出分析，进一步探讨了各方案的财务和国民经济效益差别及其原因；最后提出了本项目速度目标值的推荐方案，同时对采用该速度目标值情况下的本线功能定位、路网和时间目标值作出适应性分析。

The target speed,one of the primary technical standards in high speed railway,a core index in train running technology,and a decisive parameter in overall design,is a leading indicator that reflects the integrally technological lev-el of the railway system.The target speed adopted in design also has great impact on the strike,length,engineering in-vestment,operation cost,traction mass and transport capacity of the railway line.In this paper,started with the studies of the source of passengers in both Beijing-Kowloon and Nanchang-Ganzhou railway lines and the target time of passen-gers,given the competition between the passenger flow of this intercity line and that of expressway,as well as the most economical travel time,the target time of Nanchang-Ganzhou passenger line is put forwarded;Then the research presents the differences in technology and engineering investment at three target speed levels,furthermore the difference and rea-son of its expenditure and the subsequent state economic value are discussed respectively;Finally,the recommended tar-get speed of this project is proposed,while the adaptation of its functional orientation,route network and target time is analyzed.
