| 摘 要： | 从离心模型试验成果、超长单桩静载试验成果、工程实践及其他学者研究成果中,论证了普通单桩存在有效桩长。深入解释了有效桩长的含义,指出了与临界桩长概念有区别。在分析目前有效桩长定义基础上,提出了合理的有效桩长定义。明确了研究普通单桩有效桩长的意义及存在的问题,并提出了在一定条件下,合理确定有效桩长就是合理设计桩长。

| Abstract: | Effective length of single concrete pile is studied through test results of centrifuge model and of statical loading of super-long single pile, engineering practice, and findings by other researchers. Meanings of effective length is thoroughly explained and distinguished from critical length. A definition of effective length is reasonably put forward on the basis of current definitions. Signification and current problems of effective length of single concrete pile are analyzed. This paper believes that effective length can be taken as designing pile length under some condition. |
