| 摘 要： | 本文基于Biot动力固结方程，在BDWF模型的基础上，通过等价线性迭代不断修正土体模量以逼近土体的非线性动态响应，对建筑筒桩基础的地震反应进行了动力分析。为了分析筒桩基础的地震反应，考虑桩-土-结构的动力相互作用，将桩-土-结构地震反应分析的空间体系简化为二维问题计算。结果表明，筒桩基础桩基相对桩基于桩基有较好的抗震性能，筒桩基础的柔性改善了结构的基本周期。

| Abstract: | Based on Biot dynamic consolidation equation, this paper describes the model of the earthquake response of construction cylindrical foundation. The model can consider the soil nonlinear dynamic response by equivalence linear equation constantly amending soil module on the BDWF model. For analysis the earthquake response of cylindrical foundation, consider foundation-soil-structure interaction; make the three-dimensional system of foundation-soil-structure earthquake response analysis simplify two-dimensional question calculation. The result is that cylindrical foundation is more earthquake-resistively than pile foundation, that cylindrical foundation flexibility improves the structural basic cycle. |
