| 摘 要： | 为研究面板堆石坝的地震响应规律,采用Parkfield波作为地震动输入,在清华大学50g-t土工离心机上进行了动力离心模型试验.试验在50倍重力加速度条件下采用电液伺服离心机振动台系统完成,采用加速度传感器测量了模型不同位置动力响应的加速度时程并且测量了面板的变形.结果表明,地震最大响应发生于坝顶,该处地震动放大系数接...

| Abstract: | The study on dynamic responses of CFRD due to earthquake is presented using 50g-t centrifuge shaking table in Tsinghua university subjected to Parkfield ground motion.Acceleration time histories are recorded by acceleration transducers at different locations on the model and the deformations of the face-slab are also measured.The results show that the maximum response occurred at the dam crest where the acceleration factor is near 2.The CFRD response is amplified as the seismic wave propagating upwards thro... |
