摘    要:应用连续介质的混合物理论研究了饱和正冻土中的水热迁移问题。主要结果有:①提出了正冻土中层冰形成的一个判别法则;②将水热迁移问题化为含可动边界的非线性Burgers方程,为研究冻土水热迁移的非线性效应提供了一个理论上的出发点。

关 键 词:正冻土  水热迁移  Burgers方程

Abstract:The paper discusses heat moisture migration in saturated freezing soil on the basis of mixture theory and continuum mechanics. The main results are ①a criterion of forming layered ice in freezing soil is proposed and ② the problem of heat moisture migration is controlled by a nonlinear Burgers equation with varying boundary, which provides a theoretical foundation for studying the nonlinear effects of heat moisture migration in freezing soil.
Keywords:freezing soil  heat moisture migration  Burgers equation.
