摘　　要：结合甘肃核桃峪副井冻结工程,考虑地层温度以及相变潜热,运用有限元软件,分析了近千米深井筒冻结温度场的扩展规律。研究结果表明:数值计算温度数据与实测温度数据总体变化趋势基本一致,误差在1℃左右。所得结果为今后类似工程设计施工提供参。Combining with the deep froen shaft in Hetaoyu, considering the formation temperature and the latent heat,the expansion law of the freezing temperature field in deep frozen shaft is analyzed by using the finite element software. The influence of different frozen pipe diameters on the frozen temperature field was studied under the condition of other factors unchanged. The results show that the total variation trend of the numerical calculation temperature data is basically consistent with that of the measured temperature data,and the error is about 1 ℃. There is a linear relationship between the intersection time of the frozen wall and the diameter of the frozen pipe. The results provide reference for similar engineering design and construction in the future.
