摘要
介绍了南京地铁试验段联络通道冻结法施工过程。对冻结管施工、冻结、开挖构筑各阶段的施工技术难点及对策作了分析;同时,对施工监测数据进行总结,找到了冻结过程中温度、地面变形、冻胀压力等的变化规律。
Introduced hereby is the artificial ground freezing method used in construction of the connection passage in the trial section of metro in Nanjing, with the analysis of the difficult points and their countermeasures in the stages of construction for pipe freezing, freezing, excavation and building, and a summary of the data of construction monitor. Rules are found of variation in temperature, deformation of surface ground, frozen-heave pressure, etc.
