Abstract
Artificial tidal flat has been constructed by use of steel slag as filling materials. Three layers composed by 30-80mm steel slag, 0-25mm steel slag and coverage sand are proposed to realize stable structure without leaking of constitutive materials into lower and coarser layers.
FEM analysis of consolidation settlement by use of elasto-plastic constitutive soil models has been introduced into the construction management of artificial tidal flat. Based on predicted consolidation settlement of ground for 30 years after completion of construction, optimal heights of filling material and sand coverage are determined at the construction stages.
