长吉城际铁路速度目标值的选择

研究目的：探讨长吉城际铁路的速度目标值，分析影响速度目标值的相关因素，提出长吉城际铁路应该采用的速度目标值。研究方法：分别从运输需求、运输效率、工程投资和经济效益四方面对200、250、300km／h3个速度目标值方案进行分析研究。研究结论：结合工程建设和运营实际情况，为达到既节省初期工程投资，又为长吉城际的发展延伸预留更好的基础条件，本次研究推荐速度目标值200km／h，远期预留250km／h。

Choice of Speed Target Value of Changchun -Jilin Intercity Railway

Research purposes: The speed target value is proposed for Changchun-Jilin Intercity Railway through doing research on the speed target value and analysis of the influencing factors on the speed target value.Research methods:The analysis and research are done on the schemes of speed target values of 200 km/h,250 km/h and 300 km/h from four areas of the traffic demands,traffic efficiency,construction cost and economic benefits.Research conclusions:In combination with the real conditions of construction and operation,the proposed speed target value is 200 km/h and the condition of 250 km/h is remained for future so as to save the early construction cost and provide the better condition for the development of Changchun-Jilin Intercity Railway in future.
