VERIFICATION OF SUBMERGED BREAKWATER CONSTRUCTION METHOD TO REDUCE TUBIDITY BE USING IMPROVED DREDGED SOIL BY THE STEELMAKING SLAG -CHARACTERISTICS OF SUSPENDED SOLIDS-

Abstract

 We investigated quantitative amount and characteristic of distribute of SUSPENDED SOLIDS (SS) from mixture of dredged soil and steelmaking slag in brine with solid state and throwing method in laboratory and field experiments. We focused on fluidity (slump) about the soil and the throwing method imagined barge direct (throwing on face) and grab down (throwing in brine). In laboratory, we examined relation of ideal slump value (1-7 cm) with SS. In field, we examined characteristic of SS amount of the soil produced accordance with result of laboratory in brine every throwing method. From the above, the amount of SS from the soil can be controlled by ideal slump value and throwing method in brine.
