Abstract
In a banking process for construction of a complex, non-compaction construction has been applied in most sites, which is a method that soils are compacted by the equipment load without being compacted separately. However, there are no specific descriptions in the construction manual or specifications, so it is unclear to evaluate the excavation volume. Hence, this study is a basic study to compare the soil conversion factor at a design stage and the actual soil conversion factor of a banking ground under a non-compaction condition in order to examine the feasibility in constructing the ground for construction of the complex and to examine appropriateness of the earth work in the site by conducting an indoor, field, and load-settlement test and proposing a reasonable soil conversion factor. Under the non-compaction condition, the soil conversion factor C is set to be 1.0 at the design stage, but the result of the field test was 0.86 which is smaller than the value at the design stage. It was expected that this result would increase the banking volume, and the construction result actually showed a difference in the banking volume. Therefore, for the baking ground under the non-compaction condition, it is necessary to apply the value C suitable for the site condition after performing test by considering the site's condition and the banking height.
