根据水动力学相似和结构动力学相似原理制作了大比尺水弹性橡胶坝模型，对充水橡胶坝溢流时静力变形和动态特性进行了研究，分析了橡胶坝溢流变形规律，对水流脉动压力特性、橡胶坝的自振特性、坝袋内水压的脉动特征及橡胶坝袋的动应力和动位移进行了测试，并对橡胶坝的起伏拍动现象、共振现象和振动控制方面作了试探性的研究．在理论上，采用薄膜结构的几何非线性理论对橡胶坝的静力变形进行了计算，与试验结果符合较好
Based on the similarity principle of hydrodynamics and the principle of structural dynamics, a large-scale hydro-elastic rubber dam model was developed. The static deformation and dynamic characteristics of the rubber-filled rubber dam during overflow were studied. The law of overflow of the rubber dam was analyzed. The fluctuating pressure characteristics of the water flow, the natural vibration characteristics of the rubber dam, the pulsation characteristics of the water pressure in the dam bag and the dynamic stress and displacement of the rubber dam bag were tested. The fluctuation phenomenon of the rubber dam, the resonance phenomenon and the vibration control Made a tentative study. In theory, the static deformation of rubber dam is calculated by geometrical non-linear theory of film structure, which is in good agreement with the test results
