Abstract
Uplifting the ground by pressure injection of slurry soil is effective as a restoration method of tidal flat subject to consolidation settlement. This method ensures compatibility between maintenance dredging in ports and maintenance of tidal flats. In this study, we have made a field experiment to examine the applicability of the proposed method and confirmed the auxiliary methods to uplift the ground smoothly. By use of the distribution of S-wave velocity obtained by a surface-wave exploration, the shape of slurry soil injected in the ground has been estimated. It is confirmed that the estimated result agrees well with the volume of injected soil. In addition, the uplifting shape of ground surface in the field experiment has been reproduced by FEM analysis.
