THE RESTRATION METHOD OF THE ARTIFICIAL TIDAL FLAT USING DREDGED SOIL AND CONVERTER SLAG

Pressure injection of slurry dredged soil into the ground is one of the restoration methods for the artificial tidal flat causing the ground subsidence. To improve the injection effect, the authors invent the new type of the artificial tidal flat by using the mixed soil of the dredged soil and the converter slag between the filling soil and the covering sand. In this paper, through the field experiment test, we proved that the new type of the artificial tidal flat is effective for the injection of slurry dredged soil compared with the usual type. And we indicated the reproduction of this method by FEM analysis.
