摘要：

In the past the study of squeezing effect during pile driving focused on the single or double pile, but little on the pile group. Based on the model test, soil deformations were analyzed when the pile group were driven; then the soil lateral displacement, vertical deformation and the law of soil surface heave were obtained. It is concluded that as the distance to the pile edge increasing, the soil compaction displacement of the side surface of pile is logarithmicly decaying; the soil horizontal displacement and land surface heave are accumulated continuously; but there are sheltering effects after pressing pile, constructing order of pile plays a key role in the soil displacement; so it should be recognized in actual projects.
