This paper studies the effect of the water depth on the compaction rate and the stress of the enrockment ground with dynamic consolidation by model test,and analyzes the relationship between the compaction rate and the stress of the enrockment ground and the drop height of the pounder under anhydrous and hydrous conditions.The results reveal that the water flushed with the enrockment ground is similar to that under deep water condition.The research results provide a theoretical basis for the scale model test.
