Title: Analysis on the High Water Flow Vibration Observation of Xiaolangdi Hydropower Station No.1 Orifice Tunnel
Abstract: The paper introduced the prototype observation to the vibration of intake tower and left bank mountain in the prototype test of Xiaolangdi hydropower station 1 # high water flow orifice tunnel,and also summarized the vibration law of intake tower and left bank mountain.The results show that the vibration response of the intake tower caused by water fluctuation is the biggest when the arc door is fully open.The greater the arc door open,the larger the vibration of the intake tower response,because part of the flow energy is converted to structural vibration.There is an abrupt change process to the flow energy when arc door open from 0.8 degrees to 0.9 degrees,which results in a mutation process to the structural vibration in the 0.9 degrees and 0.8 degrees of the arc door opening.
