摘　　要：通过具体工程载体桩单桩静载试验、桩间土静载试验和单桩复合地基静载试验研究,分析了载体桩复合地基竖向承载能力和地基沉降,并根据计算给出λ、β的参考取值。结果表明,载体桩复合地基可大幅度提高地基竖向承载力并减少地基沉降,具有广阔的应用前景和显著的经济效益。Through the static load test of single pile, soil between piles and single pile and composite founda- tion in specific engineering, the theory of bearing capacity and foundation settlement of composite foundation pile were analyzed. The reference value of and is given by calculation formula. 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 broad application prospects and obvious eco- nomic benefits.
