| 摘 要： | 预制桩是桩基础工程中较常采用的一种桩型，其沉桩过程会对桩周土体产生挤压，导致桩周土体的侧向变形和隆起。本文对压桩挤土效应方面的研究成果进行了综述，重点讨论了室内和现场试验、圆孔扩张理论、有限元计算的研究概况。

| Abstract: | The precast pile is a widely used type of pile in foundation engineering. The soil surrounding the pile will be compacted during pile driving, and lateral and upward displacement will take place. In this paper research results are reviewed on compaction effect of jacked pile, specially on in-situ and laboratory experiments, the theory of cavity expansion and finite element method. |
