摘要:
利用大型振动台模型试验,测得了猴子岩高面板堆石坝缩尺模型坝的动力特性参数,包括大坝结构的自振频率、阻尼比和振型系数等;分析了多种因素对坝体动力特性的影响规律;根据模型试验相似率推算得到原型坝的相应动力特性参数.研究表明:大坝结构有相对稳定的振型;坝体的动力特性参数值受激振白噪声强度和振动历史等因素影响;水库蓄水使得模型坝结构自振频率小幅提升.这些试验结果和研究结论,可以为该坝的动力分析提供基本资料和定性参考.
Abstract:
Shaking table model tests are taken to study the dynamic characteristics of Houziyan high concrete face rock-fill dam.The dynamic characteristic parameters of the scale model dam for Houziyan high concrete face rock-fill dam are presented,such as the natural frequency of vibration,damping ratio,vibration mode,and so on.Impacts of many factors on dam dynamic characteristics are analyzed,and the corresponding dynamic characteristic parameters of prototype high rock-fill dam are obtained by the test results according to the similitude rules then.The studied results show that the dam had relatively stable vibration mode under special vibration,and dynamic characteristics of the dam are affected by many factors,such as the white noise intensity,the vibration history,and so on.Reservoirfilling slightly increases the natural frequency of the model dam.The tested results and research conclusions are important references for the seismic design of the dam.
