摘　　要：建立墩桥联合体系的空间模型 ,以墩顶横向刚度为指标来研究墩对梁体动力响应的影响 ,并进一步采用更为普遍的梁墩刚度比来研究此问题 ,提出可进行动力简化计算的参考标准。Abstract A special model of pier\|bridge joint system was established. The transversal stiffness of pier top was taken as an index to study the influence of pier on dynamic response of beam, and further study was made on this problem using beam\|pier stiffness ratio. A reference standard for simplified dynamic computation was raised.
