摘　　要：南京地铁一期工程联络通道采用冻结法施工中,对冻结盐水温度、冻土温度、地表变形等方面进行了跟踪监测;通过对监测结果进行分析研究,获得了冻结盐水温度、冻土温度、冻涨压力、卸压孔压力的变化规律,在此基础上提出了联络通道冻结施工的建议。研究成果可供其他工程参考。The application of a freezing method to construction of the connected aisle for Nanjing metro project is introduced. During the construction, the temperatures of salty water and frozen soil, the deformation of the ground surface, the expanding and releasing pressures in the soil are surveyed. The laws of the survey results are examined. Finally, based on these studies, some suggestions for guiding the construction about the freezing are proposed. Theresatts can be used for reference by similar projects.
