中文摘要：

目前，在冻结法市政工程中的应用中，多采用监测温度的方法来反映冻结工程中存在的问题。而单纯根据监测数据，并不能系统地分析冻土帷幕场的发展规律。本文依托上海长江隧道1#联络通道冻结工程，采用了温度监测、解析计算和数值计算三种方法。通过这三种方法对比和结合分析，得出冻土帷幕温度场的形成规律，并计算出冻土帷幕厚度及平均温度等指标，进而指导并确保在这种复杂工程中冻结施工的安全。

英文摘要：

At present, it＇s common to adopt the In- situ Monitoring Method to reflect some possible problems in the field of Artificial Ground Freezing （AGF） project. However, it＇s impossible to analyses the law of development of the Frozen Zone systemically according to only one method. Depending on the 1 st cross passage of Shanghai Yangtze River Tunnel, three different methods, including in - situ monitoring data, nu- merical simulation, the analytic geometry computation, are all used in the analysis of application of AGF project contrastively, to give the law of dynamic temperature, the depth of the frozen zone and the average temperature of frozen zone. It is also expected to give valuable guidance to ensure safety of Artificial Ground Freezing projects.
