摘要
结合岩滩水电站厂房振动的试验研究,提出一种水电站厂房下部结构简谐振动模型,首次进行了发电机层楼板结构的精确模态分析和水力激振荷载下的动力响应分析,各项计算结果与实测数据吻合良好。另外,也对岩滩水电站厂房楼板减振构造措施进行了分析。根据各国的评价标准和资料,探讨了水电站厂房楼板的振动对建筑物、机械、仪器设备和人体的影响及评价标准。
With the study on factory vibration of Yantan,a simple vibration harmonous model for underpart structure of power station factory building was proposed.The accurate moda analysis of generator layers and respond analysis of water conservancy shaking loads were conducted.The result of calculation and data of surveying were identical and good.Moreover,the Yantan hydroelectric station floor vibration-proof structure measures were analysed.According to the evaluation criterion and materials in the world,the impact and evaluation criterion on building,machinery,instrument and human body caused by the floor vibration of power station building were evaluated.
