【摘要】 2005年8月,龙羊峡水电站库水位突破历史高位的过程中,大坝、尾水平台等部位振动明显增大。依据现场测试成果,并借用近期的机组稳定性测试成果对大坝坝顶、廊道及尾水平台的振动情况进行了幅值和频谱分析,对振源进行了推断,最后提出了减振建议。更多还原

【Abstract】 The water level of Longyangxia Hydropower Station reached new record high in August,2005.The vibrations increased significantly in dam and the platform of tail water.In accordance with test result at site,by using recent stability test result,the amplitude and spectrum analysis are made for dam top,corridor platform of tail water.The vibration source is inferred,and vibration reduction proposal are put forward.更多还原
