中文摘要：

为了探究多层地下结构地震破坏机理,进行了三层地铁车站振动台试验。试验采用微粒混凝土模型,严格按照相似比和配筋率对模型进行加筋配置。填土采用哈尔滨地铁施工挖掘出的扰动土。装土箱采用自主研制的层叠剪切箱以减小边界效应。通过对试验加速度和应变的分析可得到以下主要结论：（1）地下结构在地震中的破坏,主要是由位移控制的;（2）多层地下结构在地震中,顶层破坏最为严重,底层破坏最轻;（3）增加延性是提高地下结构抗震性能的有效方法。

英文摘要：

The shaking table test of three-story subway station is performed to study the failure mechanism of multi-story underground structure in earthquake.Particle concrete is chosen to make the testing model,and the reinforced bar is set strictly according to the similarity ratio.A large-scale shear box is developed to reduce the boundary effect.By analysis of acceleration and strain,the following conclusions are drawn：（1）The failure of underground structure in earthquake is mainly controlled by displacement.（2）As to multi-story underground structure,the uppermost story suffers the most severe damage in earthquake.On the contrary,the lowest story suffers the slightest damage.（3）Increasing ductility is an effective method to improve the seismic performance of underground structures.
