| 摘 要： | 通过进行不同台面地震动峰值加速度输入的振动模型试验,研究了随地震动峰值加速度增大时土石坝动力特性的变化规律。此外,通过对模型不同工况振动前、后微振试验得到的动力特性比较,研究了先期振动等因素的影响。这些成果可供大坝抗震加固设计参考使用,也是验证和改善地震动力反应方法和计算程序的宝贵资料。 |

| Abstract: | Based on the vibration model tests inputted with various seismic peak ground accelerations,the variation law of dynamic characteristics of earth-rockfill dam along with the increase of the seismic peak ground acceleration is studied herein,and then the impacts from the fore-vibrations are also studied through the comparison on the dynamic characteristics obtained from the micro vibration tests made before and after the vibrations under different working conditions of the model.All the results can not be only used as the references for the seismic design of dam strengthening,but also can be used as the valuable data for the examination and improvement of both the algorithm of seismic dynamic response and the computation program concerned. |
| Keywords: | earth-rockfill dam vibration model test dynamic characteristics seismic load Wulabo Reservoir |
