文章亮点/Highlights

地震灾害的频发对地铁车站构成重大且紧迫的威胁。因此，开展精细化的车站抗震韧性评估对提升城市安全水平和保障功能持续至关重要。本研究提出了一种面向地震灾害场景的地铁车站抗震韧性概率评估框架，其通过确定车站性能曲线与对应恢复时间的积分比来实现韧性水平的精确量化。

研究采用土层-车站系统有限元模型，系统分析了场地类型、地震强度及车站结构形式对车站动力响应的影响。基于地震烈度与损伤指数的关联关系，综合考虑地震特性、施工质量等多维不确定性因素，建立了地震易损性函数。韧性评估过程整合了车站易损性、经济损失、恢复路径及可恢复性等要素，并深入探讨了结构特征、场地类型、功能恢复模式及峰值地面加速度（PGA）强度等多种因素对不同结构形式车站韧性的影响规律。

该研究为地铁网络的韧性设计和灾害适应，提供了理论支撑，有助于决策者实现资源的高效配置。

地铁车站抗震能力评估框架

摘要/Abstract

The recurring occurrence of seismic hazards constitutes a significant and imminent threat to subway stations. Consequently, a meticulous assessment of the seismic resilience of subway stations becomes imperative for enhancing urban safety and ensuring sustained functionality. This study strives to introduce a probabilistic framework tailored to assess the seismic resilience of stations when confronted with seismic hazards. The framework aims to precisely quantify station resilience by determining the integral ratio between the station performance curve and the corresponding station recovery time. To achieve this goal, a series of finite element models of the soil-station system were developed and employed to investigate the impact of site type, seismic intensity, and station structural type on the dynamic response of the station. Then, the seismic fragility functions were generated by developing the relationships between seismic intensity and damage index, taking into account multidimensional uncertainties encompassing factors such as earthquake characteristics and construction quality. The resilience assessment was subsequently conducted based on the station’s fragility and the corresponding economic loss, while also considering the recovery path and recoverability. Additionally, the impacts of diverse factors, including structural characteristics, site types, functional recovery models, and peak ground acceleration (PGA) intensities, on the resilience of stations with distinct structural forms were also discussed. This work contributes to the resilience-based design and management of metro networks to support adaptation to seismic hazards, thereby facilitating the efficient allocation of resources by relevant decision makers.
