Abstract: 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.
