本文以佛山市轨道交通二号线一期工程石洲站为例,针对“桥-建”组合双柱高架车站,进行大震性能化设计(E3地震作用分析),进而阐述了应用《城市轨道交通结构抗震设计规范》(GB50909-2014)中的相关条款指导工程设计的具体操作思路和方法。通过控制车站结构的弹塑性变形、上部结构构件的延性、主要上部结构构件和下部基础构件的性能等级以及车站主要构件的破坏机制,使车站的整体抗震性能和各构件的抗震性能在大震下得到相应的保证。本文所述实例为今后类似工程项目的设计提供了一定的借鉴。
Taking the Shizuoka station of the first phase of the rail transit project of Foshan as an example, aiming at the “double-column viaduct with the bridge-building” combination, the performance design of large earthquakes (E3 earthquake action analysis) Urban Rail Transit Structure Aseismic Design Code "(GB50909-2014) in the relevant provisions of the guidance of engineering design specific operational ideas and methods. By controlling the elasto-plastic deformation of the station structure, the ductility of the upper structural members, the performance grade of the main superstructure members and the lower foundation members and the failure mechanism of the main components of the station, the overall seismic performance of the station and the seismic performance of each component are analyzed. Get the corresponding guarantee. The examples described in this article provide some reference for the design of similar projects in the future.
