Investigation into Artificial Ground Freezing Technique for a Cross Passage in Metro

Li, Dayong / Wang, Hui

This paper studied a practical application of ground freezing in a cross passage construction of the Nanjing metro in the southeastern China. During the process of the ground freezing, temperature changes in brine, and soil; deformation changes of the ground surface and of a tunnel were monitored. Based on the field measurements, this paper revealed laws of the changes of the above factors and proposed the guidance on ground freezing method for the cross passage construction.
