The Characteristics of Temperature Field in the Cup-Shaped Frozen Soil Walls for Horizontal Reinforcement of Shield Tunneling

Abstract:

The variation of temperature distribution in the cup-shaped frozen soil wall is real-timely monitored during the whole process of the horizontal freezing reinforcement project in Yixian Bridge Station, the first phase in Line 2 of Nanjing Subway. The development characteristic of the temperature field at different depth is analyzed, and the formation time and developing speed of the frozen soil wall is further calculated. The monitoring results show that, the average growth rate of the temperature field at the interface between the frozen soil and the underground continuous wall is significantly faster than the one in the cylinder reinforced area.There is significant differences in the average growth rate of temperature field in the frozen soil wall at different area of the reinforcing plates.
