典型地铁车站结构振动台模型试验

    A Shaking Table Test Method on the Representative Subway Station Structure

    • 摘要: 为了了解地下结构在地震作用下的响应,对地铁车站结构进行了振动台模型试验,从相似关系比的确定、模形箱的设计、结构模型的制作、测点的布置、模型土的配制、地震波的加载等方面介绍了振动试验,并分析了部分试验现象.试验结果表明,在强地震作用下,地下结构会受到损害.

       

      Abstract: A shaking table test is done on a representative subway station structure to study the dynamic performance of underground structure in the earthquake. The paper introduces the test which includes the decision of model similarity ratio, the design of model box, the manufacturing of structure model, the layout of monitored points, the preparation of model soil and the loading plan of the input earthquake waves and so on. Some test phenomenan are also introduced in this paper. From the test, it concludes that the underground structure may be damaged during earthquakes.
