WebNov 29, 2024 · Dynamic compaction (DC) is a widely used method for foundation reinforcement (Menard and Broise 1975 ). In this method, a heavy tamper is lifted to a higher position and a huge energy is produced when the tamper is dropped off to a lower position, and it improves the strength of soil and reduces the compressibility of soil.
