深埋地铁线路上广泛采用立柱式车站,但其结构节点复杂,要求详细计算和精确安装。这主要是指支承在立柱上的过梁,照例它是用特殊楔形铸铁管片做成,特别是建造与旁侧隧道相邻的中央隧道非常复杂。此外铸铁管片是 Column-type stations are widely used on deep-buried subway lines, but their structural nodes are complex and require detailed calculations and precise installation. This mainly refers to the beam supported on the column, as usual it is made of special wedge cast iron pipe, especially the construction of the central tunnel adjacent to the side tunnel is very complicated. In addition cast iron pipe is
