摘　　要：通过某矿实测和数值模拟对比研究冻结管有无偏斜时三圈管冻结温度场发展过程,结果表明:冻结管无偏斜时冻结锋面扩展速度较为一致,冻结管偏斜时冻结锋面扩展速度不均匀,形成大小不一的未冻承压水仓,冻结壁交圈时间推迟一至两周;测温孔温度和冻结壁平均温度实测与模拟值随时间的变化趋势基本一致,冻结管偏斜对冻结壁平均温度和有效厚度影响较小,对井帮环向温度影响较大。Comparative study on the development process of three ring pipe freezing temperature field with and without skew freezing tube through measurement and numerical simulation in a certain mine,results show that frozen pipe is not deflected,freezing front expansion speed is relatively consistent,while frozen pipe is deflected,freezing front expansion speed is uneven,forming unfrozen pressurized water tanks of different sizes,freezing wall circle time is one to two weeks,temperature measuring hole values and average temperature of frozen wall are consistent with simulated values with freezing time,deflection of frozen tube has little effect on the average temperature and effective thickness of frozen wall,and a greater impact on the circumferential temperature of well shaft.
