| 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。

| Abstract: | 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 aseismic 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. |
