| 摘 要： | 以有限层方法和有限元方法为基础，建立了严格的群桩－土－承台结构共同作用弹性数值分析模式，该分析模式能考虑地基土的成层非均质性和正交各向异性等因素。通过与建立在Ｍｉｎｄｌｉｎ解基础上的传统分析方法的对比，证明了本文分析方法的正确性和合理性。同时，在分析中引入了结构对称性条件，并给出了具体的计算公式。

| Abstract: | Based on the finite layer method and finite element method, a elastic numerical modeling method of pile groups-soil-pile cap interaction is established. The soil models inclode homogeneous and layered non-homogeneous soils that have isotropic anistropic properties. Good agreement between the results obtained by present method and the results using Mindlin's solution proves that the method presented in this paper is correct and reasonable. The symmetry of structure is applied in analysis and give specific formula. |
