【摘要】 针对库水在拱坝结构动力响应分析中的重要影响,采用大型有限元分析软件ADINA验证了势流体单元模拟坝体—库水间耦合分析方法的正确性,并以西南某高拱坝为例,分析了考虑库水压缩性及库水位高度等条件下的坝体动力特性,获得了库水对拱坝动力特性的影响规律,可为拱坝抗震设计提供参考。更多还原

【Abstract】 Water is a very important factor in the dynamic response analysis of arch dam.Finite element analysis software ADINA is adopted to verify the correctness of applying potential flow element to simulate fluid solid coupling analytical method.Taking a high arch dam in southwest area for an example,the dynamic properties of dam body is analyzed by considering the conditions of water compression and water level height.And then the influence laws of water on the dynamic properties of arch dam are obtained.Thus,it provides reference for seismic design of the arch dam.更多还原
