The solid-fluid Interaction Analysis of Aqueduct imposed multi-point Seismic Waves
In the analysis of long-span structures like Aqueduct, if we still using the consistent input of seismic waves, it clearly not fully reflect the spatial changes about the seismic waves. Based on the solid-fluid interaction theory, this paper established two kinds of models, one is about the consistent seismic waves and the other is the multipoint input of seismic waves. According to the analysis of the response to seismic, it showed that: the velocity of seismic wave is slower the impact to the dynamic response of the aqueduct is greater when the ground is soft Therefore, in the seismic study of long-span structures, it is critical to consider the impact of the earthquakes multi-point input when the wave speed is slower. Thus the results tend to be safe and relatively realistic.
