摘　　要：通过深入分析刚性桩复合地基和考虑承台效应的复合桩基设计计算理论,以高层建筑地基基础设计计算实例为依托,总结出在承载力提高和变形降低幅度较大的地基基础设计中,大桩距疏桩基础作为一种复合桩基,克服了刚性桩复合地基和常规桩基础地基基础方案的缺点,在安全性和经济性方面均发挥了独特的优势。In this paper, an in-depth analysis was made on the design and calculation theory of both the rigid pile composite ground and the composite pile foundation considering the effect of pile caps. Based on high-rise building foundation design and calculation examples, a conclusion is made as follows, in the design of ground foundation with increasing bearing capacity and large deformation reduction, the sparse pile foundation, as a composite pile foundation, is conducive to overcoming the disadvantages of both the rigid pile composite foundation and conventional pile foundation schemes, thus giving full play to its unique advantages in terms of safety and economy.
