［摘要］通过具体工程静载试验，分析了载体桩复合地基承载受力原理、承载受力与地基沉降。应用有限元软件，并采用分段线性插值的方法，计算得出承载受力与地基沉降的关系、桩侧阻力随桩长变化的关系。结果表明，载体桩复合地基可大幅度提高桩基承载能力和减小地基沉降，具有显著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。

Abstract: Through the static load test of specific engineering, the theory of bearing stress, bearing capacity and foundation settlement of composite foundation pile were analyzed. With finite element software, the piecewise linear interpolation method was used to calculate the relationship between bearing stress and settlement and the relationship of side resistance of piles and length. Results show that the bearing capacity of pile foundation can be greatly improved and foundation settlement can be reduced with the pile with bearing base composite foundation. This kind of technique has obvious economic benefits and broad application prospects, worthy of popularizing.

Keywords: pile with bearing base composite foundation; bearing capacity; settlement; optimal carrier diameter
