从高墩桥梁的抗震难点出发，研究支座设置位置对其减震性能的影响。提出将传统的桥梁支座由墩顶转向墩的中部，墩顶与梁体固结，变高墩为低墩结构设计方案，使得高墩桥梁的抗震设计由延性设计转向减隔震设计。以某城市高架桥为研究对象，分别对刚构设计、墩顶减隔震设计、墩中减隔震设计以及墩底减隔震设计的抗震性能进行研究与评估。研究表明，中层减隔震体系桥梁可以改善并优化高烈度区高墩桥梁的地震响应。
從高墩橋樑的抗震難點齣髮，研究支座設置位置對其減震性能的影響。提齣將傳統的橋樑支座由墩頂轉嚮墩的中部，墩頂與樑體固結，變高墩為低墩結構設計方案，使得高墩橋樑的抗震設計由延性設計轉嚮減隔震設計。以某城市高架橋為研究對象，分彆對剛構設計、墩頂減隔震設計、墩中減隔震設計以及墩底減隔震設計的抗震性能進行研究與評估。研究錶明，中層減隔震體繫橋樑可以改善併優化高烈度區高墩橋樑的地震響應。

Beginning with the seismic difficulties of bridges with high piers , the paper studies the influence of the pier position on the seismic performance .It presents the structure design plan in which the traditional bridge pier changes the position from the top to the middle , the top is tightly fixed with the beam , and the high pier turns to the low one so that the high-pier bridge seismic design changes from the ductility design to the seismic design.The fly-over highway of a city is used as an example to study and evaluate the seismic performance of the steel structure design , the pier-top seismic design , pier-middle seismic design and pier-bottom seismic design.The research shows that the pier-middle seismic design can improve and optimize the earthquake responses of high-pier bridges in the high-intensity area .
