摘　　要：介绍了近几年在我国发展起来的新桩型—支盘桩的概况和工程应用情况,支盘桩在全国应用的时间比较短且应用范围不算广,对它的理论研究还落后于工程实践,可以说还处在探索阶段.分析了目前国内外挤扩支盘桩工程性状的研究进展,包括支盘桩的研究方法、承载机理、支盘间距的影响、承载力和沉降变形的计算方法和参数的引用、适用的土质条件,工程应用范围等方面的研究工作,并提出了支盘桩研究工作中存在的问题,以及对以后研究工作的展望.The general situation and project applications of pile with plates and branches which were developed in recent years have been introduced. The new kind of pile was not used for a long time and was not wildly used, so the theoretical research is behind the practice and is still in the early stage. The paper analyzed the research progress on the project behavior of pile with plates and branches home and abroad, including research methods, bearing mechanism, the effect of space between plates, calculation of bearing capacity and settlement deformation, adduction of parameters, applicable soil condition, field of application and so on. Finally, it indicated the problems in research and expectations of future development.
