摘要
通过分析小湾水电站薄拱坝中孔和表孔泄洪时坝身振动的加速度和位移数据,并分析产生振动的原因,得出表孔单孔泄洪、中孔单孔泄洪、表孔联合泄洪、中孔联合泄洪和表中孔联合泄洪时的推荐方案。
By analyzing the vibration acceleration and displacementdata of Xiaowan hydropower station thin arch dam when middle and surface outlets are discharging, and analyzing the cause of vibration, the recommend schemes are derived when only a surface outlet discharges, only a middle outlet discharges, surface outlets discharge, middle outlets discharge and surface and middle outlets discharge.
