| Research Abstract |
It has been observed that pore-air pressure affects unsaturated seepage behavior in unsaturated soils. It has also been reported that a large number of air bubbles can develop in soils after a river dike failure resulting from a flood. In this project, laboratory tests using a cylindrical soil box and a soil tank to investigate the behaviors of the pore-water pressure and the pore-air pressure under the different rainfall intensity and boundary conditions are reported. The behaviors of the pore-water pressure and pore-air pressure measured by a field monitoring are also described. As the results, these results suggest that measuring of the pore-air pressure clarifies the behaviors of pore-water pressure in unsaturated soil.
