摘要
沈阳地铁某站站后折返线基坑底板埋深约8.6m,采用排桩加钢支撑支护,明挖法施工,排桩采用800@1200钻孔桩,钢支撑采用609钢管,桩顶用冠梁将排桩连接为整体。介绍了开挖阶段钢支撑的架设及轴力的监测和分析结果。
The bottom floor of a foundation pit of Shengyang Metro works is 8.6 m deep. The foundation pit is constructed by open-cut method and reinforced by piles in row and steel supports. The piles in row consist of bored piles with 800 mm diameter and 1200 mm spacing and the steel supports consist of steel pipes with 609 mm diameter. Top beams are installed on the top of the bored piles to connect them into an integral structure. In the paper, the installation of the steel supports is described and the monitoring and analysis of the axial forces of the steel supports are presented.
