Abstract: The limited depth freezing method with four-row freeze-tubes, forming a frozen soil wall to cut off water and resist the soil pressure between the undamaged tunnel and the collapse tunnel, was used in a metro construction in Shanghai. The construction was completed successfully. This paper analyses how to use the monitored data to estimate the situation of leaking brine in freeze-tubes and judge the degree of density of the filling mortar in the tunnel. The temperature field character of the frozen soil wall was analyzed and the time of active freezing was calculated. During the cleaning in the tunnel and casting the concrete wall for water cutoff at the side of Pudong, the variation of the temperature in the frozen wall affected by the construction procedure was analyzed. It can draw a conclusion that temperature can reveal the construction quality of freezing method. Through proper redistribution of the monitoring holes, using informatized construction, studying the law of the temperature variation, the safety of the complex freezing construction can be guaranteed.

Key words: tunnel recovery, limited depth freezing, temperature field, in-situ test, informatized construction
