| Abstract: | Xiao Wan high arch dam's vibration induced by discharge flow is studied experimentally with hydroelastic model. Firstly, heaVy rubber material, which has good physical and mechanical property, is developed by the authors, and hydroelastic emulated model of l: 150 is established by the aid of computer. InteraCtions among water, foundation, arch dam and fluctuating pressure are simulated. Secondly,advanced testing mothods and software package are used to test the modals and vibration responses under several operational conditions. Thirdly, Structure dynamic analysis and back analysis on arch dam vibration induced by discharge flow are conducted by using the method of numerical simulation and experimental results. |
