本文分析了梁式桥及拱桥在历次大震中的表现,指出:1.威胁梁式桥的安全,关键是下部结构的破坏,那种认为把梁紧紧地拴在墩、台上,便可安然无恙的观念应当修正.2.拱桥在地震实践中表现良好,是耐震的,不失为地震区良好的桥型之一。文中还总结出一些抗震原则及具体措施,可供修订规范参考。 This paper analyzes the performance of beam-type bridges and arch bridges in the major earthquakes and points out that: 1. The threat to the safety of beam bridges is the destruction of the lower structures. The idea that the beams are tightly resting on piers and platforms can be safe and sound. Revised. 2. The arch bridge performs well in earthquake practice and is earthquake-resistant. It is one of the bridges in the earthquake zone. The article also summarizes some anti-seismic principles and specific measures that can be used to revise normative references.
