宁句城际轨道交通工程速度目标值的选择

宁句城际轨道交通工程加强了南京与镇江南部联系,使得句容快速融入南京中心城区,是介于城际干线铁路和城市轨道交通之间的一种新型轨道交通形式。速度目标值是城际轨道交通主要技术标准中的核心指标,它与工程的功能定位、客流特征及投资联系密切。结合宁句城际轨道交通工程的功能定位、客流特征、时间目标、线路平面条件、车站分布情况及工程造价,分析100、120、140 km/h速度目标值与本工程的适应性,选取120 km/h作为本工程的合理速度目标值。

Research on How to Select the Target Speed Value of Nanjing-Jurong Intercity Rail Transit

The Nanjing-Jurong intercity rail transit,which will enhance the connection between Nanjing and southern Zhenjiang as well as will enable Jurong to rapidly integrate in Nanjing city center,is a new type of rail transit in between an intercity railway and an urban rail transit. The target speed value is the key index among the main technical standards of the intercity urban transit,being closely related to the project's functional orientation,passenger flow characteristics and the investment cost. Based on this project's functional orientation, passenger flow characteristics, timing target, route plane, station distribution and investment cost,this paper analyzed the adaptability of this project respectively at the speeds of 100 km / h,120 km / h,and 140 km / h,and finally the speed value of 120 km / h was chosen as the rational target speed value for this project.
