Abstract

Unsaturated soil is widely distributed on the surface of earth. The soil above groundwater level is in an unsaturated state, and the pores of the soil are filled with both air and water. Many practical engineering such as earth dam, railway embankment, and airport construction involves unsaturated soils. Even beneath or near groundwater level, air cavities or large bubbles can exist between the particles of sedimentary soils. Such soil containing bubbles can also be considered as unsaturated soil. Water infiltration widely occurs in an unsaturated soil. Therefore, the study of water infiltration in unsaturated soil has important theoretical and practical significance.
