摘　　要：对建筑物-桩-土相互作用体系的地震反应分析提出了一种新的力学模型。文中用有限棱柱单元离散近场桩-土地基,分析比较了刚性基础、桩基础和浮筏基础上建筑物的弹性和弹塑性地震反应,并对考虑相互作用对结构地震反应的影响进行了分析研究。This paper presents a new mechanical model for building-pile-soil interaction system. In this paper, the part of soil near the foundation is divided with prism elements. For three kinds of building, constructed on rigid, mat and pile foundation individually, the elastic and elasto-plastic seismic responses are analyzed and compared with each other. The effect of interaction for elasto-plastic earthquake response is studied.
