This study proposes the granulation sand which expected a crystal separation function by adding a solidification reagent, cement, and urease in dredging soil. The appropriate is determined through a corn penetration test and the turbidity examination in the preliminary experiment, and this experiment is conducted to give tide fluctuation assuming the actual environment. By this experiment, in addition to the surface layer strength measurement and turbidity test in the same way as the preliminary test, it was calculated as inorganic nitrogen from the measurement of ammonia, nitric acid, and nitrous acid, and the influence on water quality was examined. Furthermore, the effects on the sediment environment were examined from the vane shear test and the measurement of the vertical distribution of nitrogen. As a result, it became clear the effectiveness of the surface solidification technology of the proposed technology.
