摘要:
近几十年桥梁减隔震技术在很多国家得到了广泛应用,已成为提高强震区桥梁抗震能力的重要手段。本文简要介绍了现有的桥梁减隔震装置,归纳了国内外经受过地震考验的多座隔震桥梁的抗震性能和震害表现,特别分析了2008年汶川大地震和2011年东日本大地震中的隔震桥梁及支座的抗震性能。根据减隔震桥梁的震害特征,总结了减隔震设计和应用是需注意的问题,包括减隔震设计方案选择、设计方法与构造要求、临近断层的设计挑战、减隔震装置耐久性等。最后展望了桥梁减隔震技术与理论的未来发展趋势,以促进对减隔震技术在桥梁工程领域的应用和发展。
Abstract:
Seismic isolation technology has been successfully applied in many countries to protect buildings and bridges from damage caused by strong earthquakes. To promote the development of seismic isolation of bridges, the state of development for seismic isolation hardware and device is introduced, seismic behavior and damage of isolated bridges and bearings during the past earthquakes were summarized. And special attentions were paid on the behavior of isolated bridges and bearings during 2008 Wenchuan earthquake and 2011 great east Japan earthquake. The lessons from past earthquakes and some issues should be considered, including designing scheme of isolated bridge, design method and detailing requirements of seismically isolated bridges, challenge in design of isolated bridges in near fault zones, and durability of seismic isolated device. So the corresponding seismic design recommendations are presented. Finally, the developing tendency of seismic isolation are introduced based on the existing research.
