摘　　要：利用ANSYS程序建立了考虑和不考虑土-结构相互作用的双塔连体结构三维有限元分析模型,对水平地震作用下的这两个模型进行对比分析。计算结果表明:在考虑土-结构相互作用后,结构的地震反应如自振周期、位移、地震剪力都受到明显的影响,应予以重视。The model of a two-tower-connected structure with the soil-structure interaction and another without considering the soil-structure interaction are founded by ANSYS program in this paper, then two models are compared and analyzed under horizontal seismic action. The results show that the seismic responses of the structure such as natural vibration period, displacement and seismic shear force are greatly affected, the influence of soil-structure interaction should be paid special attention.
