Data Analysis of Artificial Freezing Method in Subway Tunnel Repairing Constructions

By using sample railway repairing construction project taking place at Jing-Hu Railway as reference and constructing finite element formula through the study of basic thermodynamic theories and the principle of minimum potential ener-gy,the article analyzes the occurrence of temperature field during the construction and states the thickness of the freezing wall.It also stimulates the mechanic situa-tion.Results indicate that as a supportive method,artificial freezing is more than ca-pable of taking on construction projects
