常规大中桥抗震设计探讨

摘要

〔Abstract〕 The routine bridge is the most common structure in the highway, and the seismic design of the routine bridge is the key part. This article conducts the discussion of bearing, pier shear, foundation liqua-tion, damping and isolating bearing, anti-seismic construction, construction measures, and summarizes the design experience, which could provide the useful consult of the same kind bridge.%常规大中桥作为公路中最常见的结构物，数量非常巨大，其抗震设计一直是重点。本文通过对常规大中桥抗震设计中支座、墩柱抗剪、地基液化、减隔震支座、抗震措施、构造措施、系梁设置等常见问题的研究和讨论，总结设计相关经验，为今后同类桥梁的抗震设计提供有益参考。
