LARGE-SIZED EXPERIMENT FOR SLOPE STABILITY MANAGEMENT OF DREDGED SOIL IMPROVED WITH CONVERTER SLAG

Abstract

 When we construct backfill using dredged soil improved with converter slag, we need to management the slope of accumulated mound in the sea. Therefore, we conduct laboratory test and field test to determine the relationship between fluidity and slope of accumulated mound with dredged soil improved with converter slag. From the result of the test, we found that the slope can be managed by the slump value and shear strength as the fluidity index. In addition, the slope stability was shown to be able to be expressed by shear strength, saturated density and height.
