Abstract

<p> We have devised the on-site reforming method to improve a seabed clay ground by mixing with a steelmaking slag at the original position. In order to substantiate the usefulness of this method, we have been carried out field experiments of construction. As a result of experiments, it was found that it was possible to mix the steelmaking slag uniformly enough for the seabed clay ground with a natural water content, and the strength of the improved clay soil exceeded that of the indoor mixing with the hand mixer. It was also confirmed that 2.5m of the surface layer of the ground could be reformed to the improved clay soil and that an underwater embankment could be constructed. In addition, the difference in the concentration of suspended solids between before and during construction was within 10 mg/L. This confirmed that the method was capable of suppressing turbidity during construction.</p>
