Analyses of the Ground Surface Displacement under Reinforcement Construction in the Shield Tunnel End Using the Artificial Ground Freezing Method

There are stringent requirements on the vertical movement of a ground surface when using artificial ground freezing method to reinforce a shield tunnel in a city.This paper focused on the tunnel of Nanjing Metro Line Two between Yixianqiao and Daxinggong.Based on the discrete element thermo-mechanical coupling theory, the horizontal freezing reinfo
