| 摘 要： | Harlan模型的基本原理,即把温度场和水分场分别用各自的基本方程进行表述,把未冻水含量作为温度函数,建立两个方程的函数关系,得到冻土的Harlan水—热耦合数学模型.将Harlan模型应用于某铁路路基计算,比较了二场单独作用以及耦合作用的结果,分析了相互作用和影响规律.

| Abstract: | In this paper,based on the theory of Harlan model,the equations of temperature field and moisture field are found separately.Then,taking the content of unfrozen water as the temperature function,the heat-moisture coupled model is set up.Numerical simulation calculation is carried out,and the single field calculation is compared with the coupled simulation result.Finally,the interactional characteristics are studied. |
