Research Abstract

In this study, a new management method for construction and maintenance technology based on microbial functions was developed. This method can be used to improve soil strength and in-situ water insulation control. This new method was applied and analyzed in a field survey using beachrock from Japan and Srilanka. Further, laboratory tests using artificial beachrock formation were carried out.
Two main results arose from this study. First, it was found that calcium, magnesium, silica, and iron are acceptable as cement substances of beachrock. Further, calcite was found to be the most effective cement substance of beachrock originating from Kumejima Island, Japan, and Sri Lanka. Second, it was found that the bacterium Sporosarcina aquimarina, which is isolated from marine zones, is effective in improving soil strength and increasing soil liquefaction strength.
