摘　　要：通过建立正冻非饱和土水热耦合方程。对COMSOL Mutiphysics软件进行二次开发,实现多圈管冻结的水热耦合数值仿真。通过数值模拟研究得出不同时间冻结壁.温度场和水分场的发展情况,并与现场数据对比,结果表明正冻非饱和土水热耦合模型可以用于描述不同时空多圈管冻结过程中的水热分布:通过对数值模拟,得出多圈管各冻结特征点处水热-时间关系和不同时间主界面温度和冰水质量发展情况。The hydrothermal coupling of the multi-loop tube freezing was simulated by COMSOL Mutiphysics soft-ware.The development of temperature field and water field of freezing walls at different times was compared with the in site data.The proposed water-heat coupling model can be used to describe the distribution of different space-time tubes.the temperature,and ice water quality at different times.
