| 摘 要： | 本文从基岩地震反应谱衰减规律出发,研究了基岩反应谱随震级、距离的变化特征,包括基岩反应谱的第二特征周期、反应谱下降段的斜率等随震级、距离的变化规律。研究表明,震级大小对基岩反应谱的第二特征周期起着决定的作用,距离主要影响反应谱下降段的斜率,所得结论在工程抗震设计中具有一定的实用价值。

| Abstract: | In this paper,according to the attenuation law of rock response spectrum,its change characteristics with earthquake magnitude and epicentral distance is discussed,which includes the second characteristic period,the slope of the descending segments. The research shows that the earthquake magnitude is the most important affecting factor on the second characteristic period,and the epicentral distance only affects the slope of the descending segments. The obtained results can be used in practical seismic design. |
