| 摘 要： | 合成地震动一直是地震学研究中一个非常跃的领域。针对２长周期结构物抗震设计缺少宽频带强震记录的现状，利用“反射率法”和“围道积分法”等合成地震动方法对地震动长周期特性进行了探讨。结果表明：合成地震动方法是研究地震动长周特性的一个有效方法；在地震动长周期成份中，面波起着重要作用。因此长周期结构物的抗震设计必须考虑面波的影响。

| Abstract: | Synthetic earthquake ground motion has been very active domain in seismic study all along. In the light of being short of broadband strong seismic records in aseismic design of long period structures at present, using reflectance, contour integral and other methods of synthetic earthquake ground motion, the character of long period for earthquake ground motion is approached. The results show that the methods of earthquake ground motion are effective in studying the character of long period for earthquake ground motion; surface wave plays an important role in the long period component of earthquake ground motion and the aseismic design for the long period structures must take surface wave into account. |

| Keywords: | Synthetic ground motion response spectrum surface wave SH component long period structure |
