小截面静压预制桩的现场试验及其应用中的几个问题

Several Problems on the Application and In-situ Test for the small Cross Section Jacked Precast Concrete Pile

小截面静压预制桩是一项具有一定先进性的技术 ,有着广阔的应用前景。但目前其压桩的终压力估算、承载力的计算方法有待于进一步深入的研究总结。本文介绍了一个小截面静压桩基工程的现场试验、分析了压桩机理 ,总结了前人的研究方法与成果 ,并指出其局限性之处 。

The technique of small cross section jacked precast concrete piles is advanced and widely applied.At Present,the calculation of piling end-pressure and bearing capacity would be studied and summarized further.The field tests of the small cross section pile are introduced in this paper.The piling mechanism and the former past research results has been analyzed its limitations are indicated and the henceforh developing research is presented.
