摘　　要：通过简化外壁恒温条件下单圈冻结管温度场数学模型,建立了Ansys二维平面模型,运用无量纲参数主要分析了在不同影响因素组合下轴面、界面以及主面冻结温度场的冻土厚度和平均温度的发展规律,并与工程实际分析比较,以期为复杂的多圈冻结管温度场的数值模拟分析提供一些理论依据.Based on the simplified mathematical model of the thermal field with single-coil frozen pipe under conditions of external constant temperature, Ansys 2 -D plane model is constructed. By means of non-dimensional parameters, this paper chiefly analyses the laws of development of frozen-soil thicknesses and average temperatures in combination with different influencing factors in axial plane, interface and main plane frozen thermal fields, and makes a contrast with the engineering realities, so as to provide the theoretical support to numerical modeling analysis of complicated temperature field with multicoil frozen pipes.
