摘　　要：分析地震作用下饱和粉细砂层的液化机理,通过Seed简化分析法计算出地震作用下广州某区间隧道断面的土层液化点深度,讨论了土层液化点深度对盾构隧道抗震稳定性的影响,本文结论可以为盾构隧道的设计施工提供参考。Principle of satiable sand liquefaction in earthquake is investigated in this paper. Liquefaction point depth of Guangzhou subway tunnel section in earthquake is calculated using seed simplify method. Effect of liquefaction point depth to stability of earthquake resistance of shield tunnel is discussed. Conclusion of this paper refers to design and construction of shield tunnel.

关 键 词：地震 盾构隧道 液化机理 液化点深度 抗震稳定性
