摘要
通过研究渡槽结构在单向地震作用下的动力响应,利用附加质量法和流固耦合法研究渡槽结构在EL-Centro地震波不同分量下的动力响应。研究结果表明:不同地震波作用方向下,结构的动力响应不同。其中,顺槽向和横槽向地震响应较为显著,竖向最弱。对于各个方向上,水位对于结构动力响应的影响均较大,且不同的方法计算结果有所不同;研究方法同单向地震波作用。在二维地震波作用下,结构的动力响应明显强于一维地震波单独作用下的动力响应。
By studying the dynamic response of the aqueduct structure under unidirectional earthquake,this paper studies the dynamic response of the aqueduct structure under different components of EL-Centro seismic wave by using the additional mass method and the fluid-solid coupling method.The results show that the dynamic responses of structures are different under different directions of seismic waves.Among them,alongtrough and transverse-trough seismic responses are more significant and the vertical response is the weakest.In each direction,the water level has a great influence on the dynamic response of the structure,and the results of different methods are different.The research method is the same as unidirectional seismic wave.Under the action of two-dimensional seismic wave,the dynamic response of the structure is obviously stronger than that of onedimensional seismic wave alone.
