Abstract
In order to control the frost damages by frost heaving or the translation of harniful object by pore water seepage, interception layer of capilaly flow is constructed in the ground. In this paper, laboratory freezing test used by fine graind sand were put into operation and details of water migration, heat flow and water pressure change were measured under closed systein conditions. The results of experiments were compared to the results of numerical analysiaes using integrated finite difference method with coupled heat and ground water movement. It is confirmed that the Simulation of ground water movement is probable in unsaturated conditions.
