【摘要】 在简要说明桥梁高墩柱抗震特点的基础上,比较了国内外桥梁抗震设计规范的异同.然后,结合3类高墩——混凝土箱型墩柱、钢箱墩柱和钢管混凝土组合墩柱,总结回顾了国内外桥梁墩柱拟静力试验、拟动力试验和地震模拟振动台试验研究以及基于性能的抗震设计方法等方面的研究进展.最后,对桥梁高墩抗震有待进一步研究的问题和发展趋势进行了展望,可供大跨高墩桥梁抗震分析与设计以及桥梁墩柱抗震加固参考.更多还原

【Abstract】 Based on the brief introduction of seismic characteristics of the high-pier bridges,the seismic codes at home and abroad are compared.The intensive seismic study of three types of high piers,including concrete piers with box-section,steel piers with rectangular hollow section and concrete filled tube composite piers,are summarized.The seismic experimental studies of pseudo-static testing,pseudo-dynamic testing,and earthquake simulation shaking tables testing,and the performance-based seismic design and analysis are reviewed.Finally,the state-of-the-art review in this field is presented,and current research development and challenges for further study are discussed.This kind of review may be used as a reference for the seismic design and seismic analysis,seismic assessment,and seismic strengthening of the large span bridges with high piers.更多还原
