摘要
中大跨度连续梁桥固定墩系统是连续梁桥纵桥向抗震的重点。结合国内外研究成果及各国抗震设计规范,从延性抗震、能力保护设计思想出发,对固定墩桥墩、基础及支座的抗震设计进行了系统探讨,并给出了完整的设计流程。
Fixed pier system is a main part of longitudinal seismic design for large-span continuous girder bridges.Based on the princi- ple of ductility seismic design and capacity protection,seismic design of fixed pier,foundation and bearing is systematically discussed according to the research and design codes home and abroad.Finally a complete design flow is presented in this paper.
