冻结壁形成及解冻规律实测研究

Observation of the Forming and Thawing of Frozen Walls

通过实测，分析了冻结壁内温度分布规律，冻结和解冻期内冻结壁厚度、平均温度、冻结壁发展速度、解冻速度及外壁体厚占有效厚度比例与冻结时间的关系，冻结壁厚度与平均温度的关系，并得出了有关回归公式．对冻结凿井的设计和施工有着重要的指导意义．

The temperature distribution in a frozen wall is analysed. The relations between wall thickness and average temperature, the forming and thawing velocities of the wall, and the time-dependent ratio of the outside wall thickness to the effect wall thickness are presented. Some regression formulas are obtained. It is important for designing and constructing a freezing sinking.
