Enhancing Ground Improvement of Dredging Landfill in South Korea’s Western Coastal Region: Insights into Dynamic Compaction Characteristics

In this study, a dynamic compaction soil box test is performed to analyze the effect of changes in energy according pounder tamping number compactions on ground improvement. As reproducing situ challenging, 3.0 m × 2.4 1.0 used. The repetitions tested up six steps, five times at each point. change excess pore water pressure appears begin converge step three (Nd = 15) tamping. with respect using finite element analysis program AFIMEX GT-2D found have an 4.0 vertically and horizontally, similar results test. static cone penetration resistance stage increases by 1.3, 1.7, 1.1 two 10), 15), 30) tamping, respectively. depth improvement coefficient (α) ranges from 0.26 0.52, average 0.39. improved can be inferred advance correlation between repetitions, ΔN, internal friction angle. Once range determined, it used determine (weight pounder, height) given (α).
