MODEL EXPERIMENTS FOR DEFORAMTION OF FOUNDATION GROUND SURFACE BY THE SPEED OF WATER LEVEL RISE

Abstract

Model experiments of a river levee were conducted to see the surface deformation of the foundation ground by piping. The experiment condition was fixed by the difference in the speed of water level rise and the soil layer of the foundation ground. The tendency was observed that the smaller deformation was observed in the cases which the speed is comparatively low and the permeability of the soil layers was high. These results insist the possibility to find the weak section of river levee by monitoring the surface layer displacement.
