To get massive concrete sidewall hydration heat and the frozen wall’s temperature distribution law, the temperature monitor and analysis were applied in the construction process of deep frozen shaft. Combined with frozen sidewall temperature field numerical calculation finite element method, analyzed the concrete hydration heat on the impact of the artificially frozen wall in the frozen wall’s construction process. Concrete hydration heat release made rapid temperature rise of concrete, the temperature was gradually cooling down effected by the frozen wall’s low temperature and the concrete permanent supporting borders. During large release of concrete hydration heat, the frozen soil curtain was partial heating and melting, the Interface moved quickly and reached the maximum. The results showed that: the change laws of the numerical simulation and the measure point temperature were uniform, and their values were more consistent. This had a certain reference value in improving freezing construction methods and the design of deep frozen wall.
