Capillary barrier means the impermeable layer, which is observed at the boundary of two different unsaturated soil layers. The principle of capillary barrier has been applied for the ancient burial mound, capping of waste disposal site, and so on. In this paper, mechanism of capillary barrier is explained using the relationship between unsaturated permeability coefficient and suction. Soil tank test is also carried out to confirm the appearance and disappearance of the capillary barrier. Finally, the application of capillary barrier to the maintenance and management of slopes around the heritages are proposed.

Key Words: Capillary Barrier, Unsaturated soil, Countermeasure, Slope failure
