Outline of Final Research Achievements

This research project has conducted the three tasks: Motion of pore water and soil particles transported by seepage flows, shear strength during phase-change of soils, and numerical simulation of fluidized soils. The study on these topics have proposed the prediction formula of migration rate of sand particles due to seepage flows and achieved the coupled numerical analysis of flows in porous and fluid domains.
