In this study, the effects on the soil compaction were investigated through the various testing method by changing the number of layers, the number of blows per layer and drop height. The results obtained in this study were summarized as follows. 1. Soil compaction was largely influenced by maximum grain size of soil in case of small testing mold diameter. 2. The compaction effect showed best in the well graded soil. In this test, compaction effect showed the best value in the soil which contained about 30~40% of particles finer than No. 200 sieves although it would vary according to the content of coarse grained soil. 3. Though the compaction method was changed at the level of compaction energy fixed, the effect of soil compaction showed little. 4. The increment of compaction energy increased the effect of soil compaction, but over a certain limit the soil compaction showed little on the effect. 5. In the method to increase the compaction energy for the purpose of the most reasonable effect, the soil compaction effect was differently shown according to the grain size distribution of the soil.
