| 摘 要： | 给出了3种模型及不同情况下高拱坝动力特性的数值求解方案,并结合实际工程分析了不同库水模型对高拱坝动力特性所产生的影响.计算和分析结果表明:不同库水模型对坝体的自振频率、振型参与系数和振型等动力特性的影响程度相差较大;可压缩库水模型最能真实地反映库水的特性和库水对坝体动力特性的影响,可采用可压缩库水模型来求解高拱坝的动力特性.

| Abstract: | Three reservoir models and numerical schemes were given for the dynamic characteristics of high arch dams.Based on the practical projects,the effects of different reservoir models on the dynamic characteristics of high arch dams were analyzed.The computed and analytic results show that the dynamic characteristics,such as the natural frequency,the participation coefficients of vibration modes and the mode shapes,obtained by different reservoir models are quite different.The compressible reservoir model can t... |
