摘要
文中介绍了冻结法在隧道、地铁联络通道、盾构进出口以及隧道破损修复等方面的应用,地铁隧道冻结法施工期地层的冻胀现象一直是工程中所关注的焦点,根据解析法、数值分析法、模型试验法和现场实测法,对地铁隧道冻结期冻胀的研究现状进行了综述,最后提出了现行地层冻胀研究存在的问题和今后的研究方向。
This paper introduces the application of the freezing method in tunnels, subway communication channels, shield import and export, and tunnel damage repair. The frost heaving phenomenon of the formation during the construction of the subway tunnel freezing method has always been the focus of attention in the project. According to the analytical methods, numerical analysis method, model test method and field test method, the research status of frost heave in the tunnel freezing period is reviewed. Finally, the problems existing in the current research on formation frost heave and the future research directions are put forward.
