Abstract
When the drainage purification center was constructed on the weak humus ground of N=0 where groundwater is near to the surface, the influence on railway embankment caused by a ground reinforcement under the facilities was worried. The vacuum consolidation method was used because its influence was comparatively small. Railway embankment has been observing displacement. In this thesis, the feedback analysis of FEM was carried out based on the observation result of the vacuum consolidation method, and the effect of the vacuum consolidation method.
