Abstract:

Considering the practice of embankment construction ,an experimental method used to study moisture migration in unsaturated soil considering influence of the heat radiation of earth surface and rainfall is designed. According to the measurements of water content change in different depths and time under corresponding boundary condition, the rule of moisture migration of unsaturated soil is revealed due to influenced by different surface temperatures, compactness and rainfall intensities. Forthermore, the rule of moisture migration in embankment is discussed; and the conclusion that the higher compactness will reduce moisture migration rate greatly, is drawn.

Key words: embankment, unsaturated soil, moisture migration, experiment, influential factor
