| 摘 要： | 概述了桩承载力确定方法的现状和发展。特别介绍了一种新测桩法——Ｏｓｔｅｒｂｅｒｇ法的原理、应用和疑点，以及对该法的一些研究成果。设计了室内的Ｏｓｔｅｒｂｅｒｇ桩基实验装置，利用该装置进行了在桩头的压桩试验，结果表明，虽然Ｏｓｔｅｒｂｅｒｇ法的桩受力机制及桩周土的位移变形和传统的压桩试验不太相同，但该法确是一种可行的测桩法。

| Abstract: | The method for the determination if the load bearing capacity of piles is summarized and discussed in this paper. In particular, a new method, the Osterberg method, is discussed in great detail in relation to its principle, application as well as some questionable points. An indoor experimental set up for Osterberg piles is designed and used for the compressive test on the piles. Experimental results show that the Osterberg method is still applicable, though the loading mechanism of, and soil displacement around, the piles in Osterberg method are somewhat different from those in traditional compressive tests of the piles. |
