| 摘 要： | 冻结时间、冻结壁厚度和冻结壁温度场的性状是冻结法施工的关键参数。对实际工程主圈加双圈辅助孔冻结管下冻结壁的形成及其变化规律进行了数值计算。利用ANSYS大型有限元计算程序，得出了冻结壁厚度、冻结壁平均温度、冻结时间等参数，为冻结井的施工提供了必要的依据。

| Abstract: | The freeze time, the thickness and the temperature field behavior of the frozen wall are the critical param-eters in freezing construction. Inthis paper, the features of the temperature field in the frozen wall with three rows offreezing pipes are analyzed in detail with the finite element analysis(FEA) software ANSYS, referring to one engi-neering project. The thickness,the average temperature and the frozen time are obtained from FEA. |
