| 摘 要： | 通过深入分析桩基沉降组成、应力传递机制、附加应力分布、施工过程中上部结构刚度的形成及其架越效应，揭示了传统设计的桩基蝶形分布沉降与马鞍形分布反力形成的机理．均匀等刚度布桩是蝶形沉降的根源，桩顶反力马鞍形分布主要缘于地基蝶形差异沉降及基础和上部结构的刚度效应．有针对地提出了减轻这种不利分布影响的概念设计对策．

| Abstract: | The disk-shape settlement and saddle-shape reaction distribution's mechanism of pile foundation designed by traditional design concept is revealed by analyzing the settlement formation of pile foundation,the mechanism of stress transmission,the distribution of additional stress,the crossing effect and rigidity formation of the superstructure in the process of construction.The main reason of disk-shape settlement that pile foundation is arranged evenly.The disk-shape settlement and the superstructure rigidit... |
