摘要
提出了一个大型的水力学和结构动力学合一的拱坝重橡水弹性模型的模拟方法、模态分析和泄洪诱发坝体振动的实验研究成果。对我国建设中最高水坝——二滩拱坝进行了泄洪振动评价。
This paper presents a simulating method of calculating arch dam vibration for a large-scale heavy hydroelastic rubber model which embodied the principles of both hydraulics and structural dynamics. The paper also gives the modal characteristics and dynamic responses induced by the discharge flow of Er-tan Arch Dam—the highest dam under construction in China.
