| 摘 要： | 首先回顾了桩-土-结构共同作用的分析方法和我国大跨度桥梁抗震分析中对于桩基础的处理方法，然后在分析已有的桩基础简化模型的基础上，建议了一种更加合理有效的桩基础简化模型。采用各种简化模型对一座大跨度桥梁进行抗震分析，计算结果表明本文建议桩基础简化模型具有更高的精度。

| Abstract: | Firstly, the research on pile-soil-structure interaction of pile-group foundation is reviewed and the models for seismic analysis of domestic bridges with pile foundation are introduced. Then based on the analysis of the simplified models in use, a more reasonable simplified model is And on the comparision with other models, the proposed method gives a more accurate resuh for a large span bridge in seismic analysis. |
