摘　　要：论文介绍了研究挤扩支盘灌注桩-土-上部结构体系动力相互作用的方法,根据研究成果,挤扩支盘灌注桩中的支盘相当于阻尼器,可以起到减震作用。考虑相互作用的体系,结构的动力特性以及地震作用下的响应都有很大程度的变化。The paper introduced the dynamic interaction method of the soil structure system above the concrete pouring pile of the squeezed expanded support pan. According to the study achievements, the support pan in the concrete pouring pile of the squeezed expanded support pan could be a damper to reduce the strength of the earthquake. In consideration of the interaction system, the dynamic features of the structure and the earthquake response would be changed in a high degree.
