| 摘 要： | 针对土与建筑群的动力相互作用问题,该文建立了土与结构动力相互作用研究的被研究块体模型,给出一种处理建筑群与地基动力相互作用研究的波动数值方法。该方法便于研究城市中建筑群的地震响应。数值模拟结果表明:城市中建筑群的存在会使地震地面运动响应出现长尾波现象,竖向地震作用对结构的水平地震响应影响很大。

| Abstract: | To the problem of the dynamic interactions between soil and buildings,a investigated lump model is established for studying the dynamic interaction between soil and buildings.Then a numerical approach by wave propagation simulation for the study is presented.It is a simple approach to study the earthquake responses of buildings located in city.The numerical results show that the existence of buildings causes the long coda wave phenomenon during seismic ground motion,and the vertical earthquake action has a strong influence on the horizontal earthquake responses of buildings. |
