포화조건에 따른 동다짐개량효과 분석

Dynamic compaction is a soil improvement method using a heavy weight pounder dropping prescribed height, and application of this is increased recently in the west and the southern coast of Korea like as Songdo and Gunsan. However, empirical techniques to manage the construction of dynamic compaction has occurred because after dynamic compaction soil behavior and systematic data are insufficient and range of dispersion is wide. In this research We analyzed the soil improvement depth and effect on semi pervious soil with variation of saturation conditions. Research was performed four steps. In the first stage We analyzed the circumstances of design and construction site and analyzed depth of soil improvement and special things before and after construction secondly. The third stage, We evaluated effect of dynamic compaction with variation of saturation conditions.
