| 摘 要： | 给出了进行水工建筑物抗震设计时,根据水工标准反应谱合成人工地震波及修正方法,为了消除人工波中残余长周期分量的影响,通过利用最小二乘法拟合原始加速度均值,利用加速度均值对人工地震动加速度进行校正,纠正了位移时程的漂移. |

| Abstract: | A method that can simulate earthquake wave based on hydraulic design response spectrum is presented.It can be used after the initial wave is produced in the seismic design of hydraulic structure,and also can be used to modify the initial wave.In order to eliminate the influence of remaining long period components,the least square method is used to simulate average value of the primitive acceleration.The average value is used to adjust the acceleration of simulated earthquake wave,so that the shift of displacement diagram is corrected. |
| Keywords: | simulated earthquake wave design response spectrum least square method amplitude spectrum power spectrum |
