Abstract
In order to effectively use dredged soil, improved dredged soil which is mixed with steelmaking slag has been developed. Intended application areas of the improved soil are tidelands, dredging hollows and reclamation materials. Restoration method of an artificial tidal flat and development of a new artificial tideland using the improved dredged soil were studied. For the restoration method using the improved dredged soil, proposed new method was demonstrated to be effective compared with the conventional type through field construction test. For the development of new artificial tideland, proposed new structure with the improved dredged soil enables reduction in soil improvement width and increase in dredged soil quantity, and the stability of this artificial tideland was confirmed through centrifuge model test.
