摘要
以某水电站的岸塔式进水塔为例,采用ANSYS有限元仿真技术分析了该进水塔的自振特性,应用地震反应谱法研究了进水塔在三向地震动作用下的动力响应,与静力计算结果进行叠加并评价了进水塔的抗震安全性,同时利用动力时程分析法分析校核了进水塔的稳定性,可供同类工程的设计与研究参考。
Taking intake tower in hydropower station for an example, ANSYS is used to analyze self-vibration characteristics of the intake tower. And then the seismic response spectrum analysis method is applied to study the dynamic response of intake tower under three-dimensional earthquake action. At the same time, it evaluates the aseismie safety with superposition static calculating results. Finally, dynamic time-histories analysis method is adopted to verify the stability of intake tower. Thus, it provides reference for similar project design.
