以小湾工程为背景，通过水弹性模型实验，判断高拱坝泄洪所引起的振动和影响．采用自已研制的物理和力学性能优良的加重橡胶材料．在计算机的辅助下，建成了１：１５０比尺的水弹性实物模型，完善了对库水－地基－坝体－脉动荷载相互作用的模拟；采用先进的测试手段和分析软件包，对该模型的模态和多种工况泄水响应进行了全面的测试与分析，并采用计算机数值模拟与实验成果相结合的方法对坝身泄洪振动进行了结构动力分析及反分析和反馈分析．构成全仿真模型，都取得了满意的结果．
Based on the Xiaowan project, the hydro-elastic model experiment is conducted to determine the vibration and influence caused by flood discharge of the high arch dam. Using their own developed physical and mechanical properties of the heavier rubber material. With the aid of computer, a 1: 150 scale hydroelastic model was built to simulate the interaction of reservoir water - foundation - dam body - pulsating load. Using advanced testing methods and analysis software package, Mode and a variety of conditions of the drainage response of a comprehensive test and analysis, and the use of computer numerical simulation and experimental results of a combination of methods to dam body flood discharge vibration structural analysis and dynamic analysis and feedback analysis. Constitute a full simulation model, have achieved satisfactory results.
