| 摘 要： | 假设近场地面运动由体波产生（忽略面波的影响），根据弹性半空间的平面谐波理论，提出了利用平动分量加速度记录合成地面转动加速时程的方法。该方法考虑了由于实际介质的不均匀性而产生的地震波频散现象。

| Abstract: | Supposing that the near field earthquake motion is produced by body waves, the paper proposes a method to estimate the rotational component time history of artificial earthquake motion in terms of the translational motion components based on the theory of elastic plane wave propagation. The method considers that the frequency dependence characteristics of seismic wave velocity is caused by the nonuniformity of propagation media. |
