摘要
针对成层地基，用样条有限元与半解析无限元耦合法分析水平方向无限伸展的地基土，对结构－地基－结构进行了地震反应分析，并在分析中考虑了地震波存在的衰减和相位差。
In this paper,the foundation is divided into finite layers in vertical direction. The spline finite element and the semi analytical infinite element are used to investigate the infinite soil. The decay and the phase difference of the earthquake wave are considered when building foundation building interaction system is investigated. Some conclusions on the earthquake responses of building foundation building interaction system are obtained.
