| 摘 要： | 以济南市轨道交通R1线演马庄西站为工程背景，采用振动台试验研究土体自由场、两层两跨车站结构土体-结构体系在典型地震波下的动力特性。结果表明:在自由场试验中，随着输入地震波峰值的逐渐增大，相同位置的加速度放大系数逐渐减小；在土体-结构体系试验中，由于地下结构的存在，地震波在传播过程中放大效应与自由场存在差异，且不同类型的输入波产生不同的加速度放大系数变化规律。

Study on Earthquake Behavior of Metro Station in Jinan City by Shaking Table Test |

| Abstract: | Taking the west Yanmazhuang Station of Jinan Rail Transit Line R1 as the background, shaking table test was used to study the dynamic properties under typical seismic wave in the free field of soil mass, and of soil-structure system in the two-storey two-span station structure. The result shows that, in the free field test, the amplification coefficient of acceleration at the same position decreases gradually as the input peak of seismic wave increases gradually; in the soil-structure system test, due to the existence of underground structure, the amplification effect during the spread of seismic wave has difference from that in the free field, and different kinds of input wave may produce different change law of acceleration amplification coefficient. |
