STUDY ON VERIFICATION OF PORE WATER PRESSURE IN STATE OF RAISING UP WATER LEVEL USING FLUID AND SOIL WEAK COUPLING MODEL

Abstract

 In this study, we applyed Dupuit-Forcheimer's law to the processing of the fluid side porosity of CADMAS-STR. The result were compared with the result of physical experiments. It was found that the calculation and the experiment result showed consistent value for the seepage flow velocity under the sheet pile. The validity of this method was therefore confirmed. In addition, pore water pressure was consistent with the calculation and the experiment. From this result, it was found that reproducing the seepage flow velocity by applying Dupuit-Forchheimer's law, it is possible to estimate pore water pressure exerted by underground water.
