广州地铁海珠广场站换乘设计与实施

Design and Construction of Haizhu Square Interchange Station of Guangzhou Metro

由于线网完善和城市规划调整,地铁建设无预留换乘节点的改造换乘站数量在增加。如何解决深埋、编组不匹配,无预留节点等改造换乘问题,成为地铁建设新的挑战。广州地铁6号线海珠广场站存在深埋、编组不匹配,无预留节点和周边环境复杂等问题,通过对不同换乘形式进行分析,在建筑设计上采用了L型平面换乘方式、单循环换乘的客流组织模式、台-台加厅-厅组合通道换乘形式;在结构设计上,通过采用明暗结合法满足了古树保护、历史建筑保护以及既有运营线安全等多项建设控制条件,成功实现了城市中心区复杂条件下的地铁换乘设计和建设问题。设计方法和实施经验对该类型的换乘车站具有借鉴意义。

The rehabilitation of Metro stations without reserved interchange node increases with the development of Metro network and adjustment of urban planning. The rehabilitation of deep-buried Metro stations without reserved interchange node and with unmatched marshalling in complex environment is a new challenge. In the design of Haizhu Square Station on Line No. 6 of Guangzhou Metro,L-shaped plan interchange mode,single-cycle interchange mode of passenger flow and platform-platform ＋ hall-hall interchange mode are adopted; in structural design,open-cut and mining method are used. A series of interchange problems have been solved. The study results can provide references for similar projects in the future.
