通过分析《城市轨道交通结构抗震设计规范》《地铁设计规范》《建筑抗震设计规范》对地下车站结构抗震等级的规定,结合工程实例,具体分析了不同抗震等级对地下车站工程造价等的影响,探讨了在安全使用的前提下,如何经济合理的确定轨道交通地下车站的抗震等级,为今后的工程设计提供参考。
By analyzing the provisions of Seismic Design Code for Urban Rail Transit Structure, Code for Design of Subway Design and Code for Seismic Design of Subway Buildings, the rules for the seismic rating of underground station structures are combined with engineering examples to analyze the impact of different seismic levels on the construction cost of underground stations. This paper discusses how to determine the seismic rating of the underground station of rail transit under the premise of safe use and provides a reference for the future engineering design.
