【摘要】 以某高速公路项目4-30m小箱梁及4-20m空心板桥为例,对液化场地条件下大中桥抗震设计的模型建立、抗震分析、结构配筋、抗震验算、抗震措施等内容进行介绍,并对抗震设计过程进行较全面的梳理,总结规律,提出建议,为今后此类桥梁的抗震设计提供参考。更多还原

【Abstract】 In this thesis,one 4- 30 m small span box girder and one 4- 20 m hollow slab bridge in certain highway are taken as examples to analyze the model development,earthquake resistance,structural reinforcement and aseismatic construction for big and medium bridges on liquefiable ground. The whole earthquake- resistance design has been presented and summarized,based on which relevant suggestions are given to similar cases in the future.更多还原
