地震作用下水-结构-土动力相互作用分析

该文基于ABAQUS建立了地震作用下水-结构-土系统数值模型,分析了地震动水平和竖向作用时在不同水深条件下水-结构、水-土相互作用对结构、土体和水体响应的影响.结果表明,水平地震动作用下水-土相互作用对系统响应的影响远小于水-结构相互作用,且对水、土、结构响应的影响较小,可忽略不计.竖向地震动作用下水-结构相互作用对系...

ANALASIS OF WATER-STRUCTURE-SOIL DYNAMIC INTERACTION UNDER EARTHQUAKES

In this paper, we establish an efficient numerical model of water-structure-soil systems under seismic action based on ABAQUS to analyze the influence of water-structure and water-soil interaction on the response of the structure, soil and water under different water depths. Under the action of horizontal ground motions, the results show that the influence of the water-soil interaction on the response of the system is much less than that of the water-structure interaction, and that the influence on the response of the structure, soil and water is negligible. Under the action of vertical ground motions, the effect of water-structure interaction on system response is much less than that of water-soil interaction, and that the water-structure interaction has little influence on the system response. Therefore, only the water-soil dynamic interaction needs to be considered in theoretical simplification analysis.
