摘　　要：结合溪洛渡拱坝泄洪振动水弹性模型,详细分析了坝基、上、下游,坝肩的基础模拟范围及弹性材料物理特性对水弹性模型研究的影响,全面模拟了“坝体—基础—库水—动荷载”四位一体流固耦联的振动系统,将数学模型与物理模型结合起来,实现了既满足水动力学相似又满足结构动力学相似的全仿真模拟,为高拱坝。The present research is combined with the Xiluodu Dam.FEM is adopted to study foundation’s simulated scopes including the base,up-stream and down-stream sections,and the bank.The material parameters are also ana-lyzed.In the paper,the math model and physics model were combined to meet the fluid dynamical and structure dy-namical conditions.By this way,a new method is found to analyze the sluice vibration of high dams.
