Brief Introduction on Improvement Engineering Design Scheme of Pedestrian Subway in Guangshan Road Tianhe Passenger Station

城市过街通道由于地面交通繁忙、各类管线较多、地面建筑物拆迁困难、施工面狭窄,造成隧道施工周期较长。不同施工周期通道之间的衔接,对先期施工隧道的处理等问题较突出。通过对广州市广汕路天河客运站路段人行过街隧道完善工程项目设计方案的介绍,提出了对解决类似问题的方式方法,作为解决同类问题的参考。

For the urban crossing-street tunnel, its construction period is longer because of heavy ground traffic, more pipelines, hardly removed ground buildings and narrow construction field. The join between the different construction period channels is very important for the treatment of the earlier construction tunnel. The article introduces the improvement engineering design scheme of the pedestrian subway in Guangshan Road Tianhe Passenger Station, and puts forward the methods to solve the similar problems for reference.
