| 摘 要： | 通过模型试验，探讨水深对重锤夯击抛石后夯沉率及抛石应力的影响，以及有、无水情况下抛石夯击夯沉率和抛石应力随落距的变化关系。试验研究成果表明：水面与抛石面齐平的情况与有水的夯击效果相近，为缩比尺模型试验中消除边界效应及水深影响提供了理论依据。

| Abstract: | 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. |

| Keywords: | model test dynamic compaction stress of enrockment ground compacted rate |
