摘　　要：为了研究城市新区轨道交通骨干线路的前期研究特点,以西安地铁16号线为例,总结了贯穿城市新区的轨道交通骨干线在线路功能、运营方案、技术标准、局部路由、开发结合、车站规模等方面的特征。西安地铁16号线为贯穿西咸新区中轴线的首条大运量骨干线路,前期研究的主要特点有:规划引导型线路,受控规划条件,工程条件可控;不同设计年限客流强度差异较大,运营组织方案研究复杂;一期建设长度过短引起系统研究范围广、技术标准确定难度大、预留接口灵活度要求高;考虑兼顾重要分散客流点的局部选线方案论证复杂;线路契合城市功能,设计标准高,新技术应用广泛;与地下空间开发衔接紧密;特定站点规划强度极高,采用超前设计理念提高车站抗风险能力等。同时,针对城市设计与轨道交通规划衔接、重要客流集散点与轴线功能关系分析、土建设计理念和设备系统预留思路提出了相关建议。In order to study the characteristics of the preliminary research on rail transit backbone lines in the new urban district, this paper takes Xi’an metro line 16 as an example to summarize the characteristics of such lines in terms of line function, operation scheme, technical standards, local routing, development combination and station scale. Xi’an metro line 16 is the first large capacity backbone line running through the central axis of Xi’an-Xianyang new district. The main characteristics of the preliminary study are as follows. The line guides the realization of planning, which is controlled by planning conditions and not by engineering conditions. The difference of passenger flow intensity in different design years leads to the complexity of the research process of operation organization scheme. Due to the exceptional short length of the first phase construction, extensive system research has to be conducted with difficulties in determining technical standards and high requirements for reserved interfaces. The local route scheme is complex in view of important dispersed passenger flow points. As the line concerns the urban functions, high design standard and new technology are adopted. Advanced design concept is employed to improve the anti-risk ability of stations with high planning intensity. In addition, this paper puts forward some suggestions on the connection between urban design and rail transit planning, on the relationship between important passenger distribution points and urban axis, and on the civil engineering design and equipment system reservation.
