我国对地铁区间隧道的抗震分析研究，长期以来多是采用等效静力法来模拟地震对区间隧道的作用，由于隧道结构与地层之间的特殊关系，这种分析结果与实际出入较大，未能真实反映区间隧道与地层的相互作用，文章结合国内外地铁区间隧道抗震研究及相关规定，提出地铁抗震验算方法，可为地铁抗震设计提供参考。
我國對地鐵區間隧道的抗震分析研究，長期以來多是採用等效靜力法來模擬地震對區間隧道的作用，由于隧道結構與地層之間的特殊關繫，這種分析結果與實際齣入較大，未能真實反映區間隧道與地層的相互作用，文章結閤國內外地鐵區間隧道抗震研究及相關規定，提齣地鐵抗震驗算方法，可為地鐵抗震設計提供參攷。

The paper makes anti-earthquake study and analysis of metro tunnels in China, the long-term use of equivalent static method to simulate the effects of earthquakes on tunnel. Due to special relationship between tunnel structure and stratum, the results of this analysis have more errors as compared with the actual, failing to truly reflect interaction of running tunnel with stratum. With anti-earthquake study on metro tunnel and related rules and requirements abroad and in China, the paper proposes the method for metro anti-earthquake calculation which can provide a reference for the future metro anti-earthquake design.
