主要从三个方面对白石桥南站围护即盾构调头设计进行了总结:(1)对换乘节点大尺寸基坑的两种主要设计方案进行了比选,指出了它们各自的优缺点;(2)车站施工场地狭小,通过合理的基坑开挖步序安排,有效地解决了施工场地不足的问题;(3)受车站施工场地及车站上方高压线的限制,大型起重设备无法安装,盾构调头只能在车站内进行,对站内调头方案进行了详细介绍,并指出了该方案的设计要点。
Mainly from three aspects of the Baishiqiao South Station shield that is U-turn shield design: (1) The two major design options for large-size foundation pit transfer were compared, pointing out their respective advantages and disadvantages ; (2) The construction site of the station is small and the excavation sequence of the foundation pit is reasonable, which effectively solves the problem of insufficient construction site; (3) Due to the restrictions of the station construction site and the high voltage line above the station, the large-scale lifting equipment can not be installed , Shield U-turn can only be carried out in the station, the station U-turn programs were described in detail, and pointed out the design of the program points.
