| 摘 要： | 本文通过美国强震记录,按照中国场地类别划分方法进行场地分类,研究不同类别场地条件对地震动持时的影响(70%能量持时)。分析表明,场地条件对持时的影响非常大,总体来说,随着震级的增大持时变长,在同一震级时,各类场地随震中距的的变化趋势差别较大,并且竖直向与水平向的变化趋势很相近。 |
| 关 键 词： | 场地条件 持时 震中距 震级 |

| Abstract: | Through analysis of strong earthquake records from U.S.A. and according to Chinese site classifying method, this article mainly studies the effects of different kinds of site conditions on earthquake ground motion duration (70% energy duration). Our results indicate that site condition has great influence on duration time. In general, duration increases with the increase of magnitude. With same magnitude, there is an apparent changing tendency difference with the change of epicenter distance. Moreover, such changing tendencies are much similar both in vertical and horizontal direction. |
| Keywords: | Site condition Duration Epicenter distance Magnitude |
