摘　　要：结合现场静载试验和有限元计算,分析了复合载体夯扩桩的承载力性状。实践证明,复合载体夯扩桩可大幅度提高桩基承载能力和减少地基沉降,具有明显的经济效益和广泛的应用前景,是一项值得大力推广的技术。Combining with finite element analysis and the field static load test, the bearing capacity characteristics of the ram-compaction piles with composite bearing base are analyzed. The practice shows that the new pile foundation can not only increase the bearing capacity of the ground, but also reduce the settlement. Because it＇s effective in ground treatment and also economical, the technology is worthy to be spread greatly.
