土壤水热耦合运移的数值模型研究是在二十世纪五十年代在等温水分运动模型的基础上发展起来的 ,该模型的建立不仅可用于预测农田水热的分布情况 ,从而为农业生产决策服务 ,而且可用于工业生产建筑中的地下产热问题和垃圾填埋场土地填筑中垃圾腐化产热问题的解决 ,因而具有广泛的应用价值 .本文对五十年代以来国内外土壤水热耦合数值模型的主要研究发展进行了介绍 ,并指出现今的模型应注意的问题 .
The numerical model of soil water-heat coupling movement was developed in the 1950s on the basis of isothermal water movement model. The establishment of this model not only can be used to predict the distribution of water and heat in farmland, Decision-making service, and it can be used to solve the problem of underground heat production in industrial production buildings and the problem of waste heat generation and waste heat treatment in landfill landfill, so it has a wide range of application value.In this paper, The main research development of the coupled numerical model is introduced, and the problems that should be noticed in the present model are pointed out.
