| 摘 要： | 本文研究桩基-非线性框剪结构相互作用体系的地震反应。其中上部框架和剪力墙结构分别用门型单元和四弹簧墙单元进行分析；桩基阻抗函数通过单桩阻抗和动力相互作用因于求得。采用频-时域混合法求解体系的动力方程，本文研究了在桩基-框剪结构相互作用体系地震反应分析中，桩基阻抗的频率相关性对结构地震反应的影响，并从土体剪切波速和地震波强度两个方面，研究了土-桩-结构相互作用对框剪结构地震反应的影响。

| Abstract: | The paper investigates the seismic responses of pile-nonlinear frame-wall interaction systems, in which the frame and wall are respectively dealt by door-like elements and four-spring wall elements and the impedance funtions of pile groups are comPuted by using the impedance function of single pile and dynamic interaction factors. By way of hybridfrequency-time-domain procedure, the authors investigate the efha of frequency dependence of impedance functions of pile groups on the seismic response of structure. The authors also investigates the effects of soil-pile-structure interaction on the seisAnc responses of structures based on the shear wave velocity of soil and intensity of seismic motion. |
