为验算某水电站进水塔的抗震稳定性,基于ANSYS软件,采用振型分解反应谱法研究了进水塔结构在三向地震作用下的动力响应。然后将动力计算结果与静力计算结果叠加,通过ANSYS的二次开发技术求得不同工况下塔基面轴力、剪力和弯矩,进而分析了进水塔结构的抗滑、抗倾覆、抗浮稳定性。结果表明此进水塔的抗震稳定性符合规范要求,可供同类工程的设计与研究参考。

In order to check the seismic stability of the intake tower in a hydropower station,ANSYS is used to analyze the dynamic response of the intake tower under three dimensional earthquakes through mode-superposition response spectrum method.And then,by the superposed results of dynamical and static calculations,the axial force,shear force and bending moment could be got by the secondary development based on ANSYS.Finally,the anti-sliding stability,anti-overturning stability and anti-floating stability are evaluated.The results show that the seismic stability of the intake tower is in compliance with requirements,which could provide references for similar project design.
