摘　　要：抽水蓄能电站机组运行产生的水力压力脉动不仅能引起厂房结构振动,还能引起输水管道区域振动。本文通过对两座大型抽水蓄能电站输水管道区域的振动及噪声监测数据进行分析研究,表明振动影响介于无感振动与轻微有感振动之间,不会引起区域周边产生结构安全问题,但是振动会引发附近山谷和建筑物内产生结构性噪声影响。建议新建抽水蓄能电站在规划选址时需要关注此类问题,输水管道选择远离或避开居民区或者加大埋深。The hydraulic pressure pulsation caused by the operation of pumped storage power station units can not only causes the structural vibration of power house,but also causes the regional vibration of water transmission pipeline.In this paper,the vibration and noise monitoring data of the water transmission pipeline area of two large pumped storage power stations are analyzed and studied.It shows that the vibration impact is between non inductive vibration and slight inductive vibration,which can not cause structural safety problems around the area,but the vibration maybe cause structural noise impact in the nearby valley and buildings.It is suggested that such problems should be paid attention to in the planning and site selection of the new pumped storage power station,and the water transmission pipeline should be far away from the residential area or increase the buried depth.
