摘要
为了探讨抽水蓄能电站输水管道区域环境振动的问题,结合实际工程的环境振动监测资料,采用Midas-GTS软件分析抽水蓄能电站输水管道区域环境在不同工况下的振动影响,并提出合理的减振措施。研究结果表明:库区上游靠近机组的区域环境振动分贝值均大于库区下游,库区下游靠近居民区的环境振动分贝值均大于居民区环境振动标准值,且严重影响居民的正常生活。由于抽水蓄能电站区域环境振源复杂,填充沟措施效果显著,且易施工,对类似的抽水蓄能电站工程具有一定的借鉴意义。
In order to explore the issue of environmental vibration in the water transmission pipeline ar-ea of pumped storage power stations,combined with actual engineering environmental vibration monito-ring data,Midas GTS software is used to analyze the vibration impact of the water transmission pipeline area environment of pumped storage power stations under different working conditions,and reasonable vibration reduction measures are proposed.The results indicate that the decibel values of environmental vibration in the upstream area near the unit are higher than those in the downstream area,and the deci-bel values of environmental vibration in the downstream area near the residential area are higher than the standard values of environmental vibration in the residential area,which seriously affects the normal life of residents.Owing to the complex environmental vibration sources in the pumped storage power station area,the filling ditch isolation measures have significant effects and are easy to construct,which has certain reference significance for similar pumped storage power station projects.
