摘要:

为实现城市轨道交通车站与综合交通枢纽的无缝衔接，在新建高铁站与机场时，待建的城市轨道交通车站土建结构一般与其同步设计、同步实施，并预留后期线路衔接条件。在进行城市轨道交通车站预留工程时，应使预留工程具有较强的包容性，避免后期因线路实施时对预留工程进行改造，造成线路功能不合理及工程投资浪费。以青岛地铁6号线青岛西站站预留工程为例，从研究背景、预留工程概况、列车折返及其改造方案等方面进行分析。研究结果表明，青岛西站站预留工程宜采用有效站台不动的站后折返方案。该方案改造工程虽存在一定风险，且距离已运营的高铁距离较近，协调难度较大，但考虑其可分别使用两个站台上、下客，对高铁站大客流适应性较好，且站台公共区楼扶梯布置均匀、设备用房不需重新调整布置，故车站使用功能较好。

Abstracts:

To realize the seamless connection between urban rail transit station and comprehensive transportation hub, when new high-speed railway station and airport are being built, the civil structure of planned urban rail transit station is generally designed and implemented simultaneously, having connection conditions for future line reserved. When carrying out reservation project, the engineering should be relatively inclusive, so as to avoid reconstruction in future line implementation, resulting in unreasonable line function and waste of engineering investment. Taking the reserved project of Qingdao Metro Line 6 Qingdaoxi Railway Station as an example, analysis is carried out from aspects including research background, pre-buried project overview, turn-back and reconstruction scheme. Research results show that the scheme of turning-back after station without moving the effective platform should be adopted in the station reserved project. Although certain reconstruction risks exist in this scheme, and the close distance from operating high-speed railway increases coordination difficulty, the scheme allows use of two platform for passengers boarding and alighting respectively, giving adaptability to the mass passenger flow of high-speed railway station. The stairs in the platform public area are evenly arranged, and the equipment room does not need to be rearranged.
