摘要
本文以飞来峡溢流坝系统（包括闸墩、胸墙、导墙结构）泄洪振动问题为背景，采用水力学和结构动力学相似条件同时满足的“二合一”模型——重橡胶水弹性模型，较现代的方法进行模态和过水激振测试和分析，并与计算机数值计算结果进行了对比研究．本研究不仅对解决大功率、低弗氏数、高淹没度的泄水结构系统水流诱发振动问题具有现实意义，同时对于高速水流诱发各种水工结构的振动研究也提供了一个较完善的方法．
This paper introduces a heavy rubber hydroelastic model, which satisfies the requirements of similarity criterion of both hydraulics and structure dynamics. Modern methods are adopted to test and analyse the model characteristics and dynamic responses induced by the discharge flowing through FeiLaixia overnow dam including pier, breast wall and guide wall.The experimental results are compared with the calculated results. This study not only is applicable to the structural vibration induced by discharge flow with large power, low Froude number and high submergence, but also offers a good method for predicting various hydraulic structure vibrations induced by high velocity flow.
