    ANALYSIS OF VERTICAL BEARING CAPACITY OF SINGLE PILE TO ROTARY CAST-IN-SITU PILE IN A PROJECT OF SOUTHEAST ASIA

    • 摘要: 桩基静载试验在确定单桩极限承载力方面是常用的方法,目前针对国内工程的相关研究较为丰富,但在海外工程方面的实例则相对较少,而且一般的试验研究未达到桩基受力的极限状态,试验资料不够完整,因而进行桩基的破坏性试验是很有必要的。为此,该研究结合东南亚某项目实例,对该工程子厂房的6根试桩,进行了单桩竖向抗压极限承载力的现场破坏性静载试验,采用试桩的Q~t和S~t曲线分析了单桩竖向承载力的试验过程,对单桩竖向极限承载力按相关规范进行了综合确定,为该地区同类工程积累了经验,也为该类型桩的进一步研究提供了宝贵的试验资料。

       

      Abstract: Pile static load test is a common method to determine ultimate bearing capacity of single pile, the research about domestic project is abundant at present, however the cases from overseas projects are scanty, and most of the studies did not reach limit stat of pile foundation, test data were incomplete, so it is necessary to carry out destructive tests of pile foundation. Therefore, the study, combining with a project of Southeast Asia, finished destructive test of single pile ultimate bearing capacity of vertical compressive by static load test to 6 test piles of subsidiary factory in this project, analyzed the process of the vertical ultimate bearing capacity of single pile test by Q~t curve and S~t curve, determined single pile vertical ultimate bearing capacity according to the specifications, accumulated experiences for similar project in the region, contributed the precious experiment data for further research.
