【摘要】 利用大坝强震观测系统记录的强震事件资料,进行三维空间的频谱、加速度、速度、动力放大倍数分析,从而得出地震波在混凝土重力坝中不同高程、不同方向、不同介质中的加速度、速度反应特性、频谱特性和动力放大特性,为以后工程抗震设计和结构安全性设计提供参考。更多还原

【Abstract】 Based on the recorded earthquake events, the paper analysed the spectrum, acceleration, speed and power magnification of seismic wave in three-dimensional space. As a result, the characteristics of spectrum, acceleration, speed and power magnification on different levels, in different directions and materials were gotten, worthy reference for seismic design.更多还原
