摘　　要：采用样条子域法、半解析无限元法和直梁的弯剪单元模型相耦合的方法 ,对于带有多层地下室的桩承高层建筑与周围土体组成的体系在地震作用下的动力相互作用反应时行了分析研究。算例表明 ,本文方法具有输入数据简单 ,计算量较小 ,精度较高的优点 。In this paper,response of the interaction system,which includes pile-supporting tall buildings with multistoried basement and the adjacent medium of soil,is analyzed and investigated under the action of earthquake through the coupling of the spline subbomain method,semi-analytical infinite element method and the bend-shera model of beam element.The results show that the adopte method not only has the advantages of less input data,less computation efforts and higher satisfactory precision,but also better reflects the dynmic properties and the internal mechanism of this type of building in engineering,considering the interaction between the building and its adjacent ground.
