摘　　要：西安北站至机场铁路是西安市区与机场旅客交流的城际轨道交通线路,根据其运营期直达客流比例较大的客流特点,结合国内其他机场线路速度目标值,提出西安北站至机场线路速度目标值方案。从速度目标值对线路走向、建筑限界、运行时间、运行能耗、站间距离、系统设备、环境影响和工程投资等方面的影响进行综合分析,最终推荐运营费和投资较节省的100 km/h速度目标值方案,平纵断面预留速度目标值为120 km/h的条件。The Xi’an North Station-Airport line is an urban rail transit line of passenger transportation which connected with Xi’an city area and airport.According to passenger flow characteristics of its operating through passenger transportation,and combined with other speed object value of airport line in China,this paper puts forward the speed object value program from Xi’an North Station to Airport.The paper also makes comprehensive analysis on the influence of speed object value on track alignment,construction clearance,operation time,operation energy-consumption,distance between stations,system equipment,environmental influence and engineering investment,the program of 100 km/h speed object value is recommended finally for its less operation cost and investment,and the condition of pre-reserved speed object value on plane and profile section is 120 km/h.
