摘要
济南轨道交通联络通道采用冻结法施工,经综合分析表明,冻结法施工在富水砂卵地层中安全可行。形成的冻结体整体性和封水效果好,联络通道两面开挖方案可行,分析施工停电停冻对冻结帷幕的发展影响,可供类似工程参考。
Ji’nan rail transit connecting tunnel was constructed by using freezing method. After general analysis, it was found that freeing construction method is safe and feasible in rich-water sandy cobble stratum, that the frozen structure has favorable integrity and waterproofing performance, and that excavation on both sides of the connecting tunnel is feasible. This paper analyzed the influence of power failure and freezing failure on freezing curtain, providing reference for similar projects.
