摘　　要：本文结合具体的工程实践和课题研究,探讨了夯扩桩基承载力及荷载传递的作用机理,在福州地区闽江冲积洲中粗砂地基中夯扩桩施工技术的工程应用中进行现场测试和成果分析,对夯扩桩性状、技术特点等做了总结,通过现场的检测成果比较对设计和施工提出合理的建议,为进一步推广应用提供了依据。Based on the theory study and engineering practice, this paper analyses the mechanism of bearing - force and load - transmits of rammed bulb pile. Especially in medium and coarse sand of alluvial island lied in Fuzhou Minjiang river area, we can approach some properties and technical conditions through field test and data analysis. Combined with field testing data, some rationalization proposals on design and construction are raised and basis for popularization and application are provided in the end of the thesis.
