伽师-巴楚地区中强地震加速度衰减关系研究

Research on the Acceleration Attenuation Relationship of Moderate-strong Earthquakesin Jiashi--Bachu Region

摘要:

采用直接估计经验方法对巴楚-伽师地区1996-2003年126条M≥4地震的加速度记录进行回归分析,得到中强地震在土层场地上的水平向和垂直向加速度衰减规律。其中水平向加速度衰减关系适用的震级范围为4.0≤M≤6.9,垂直向为4.0≤M≤5.9。

Abstract:

Using the experiential method, the horizontal and vertical acceleration attenuation relationships of moderate-strong earthquake in soil site are obtained by directly regressing the acceleration recordings of earthquakes（Ms≥4） from 1996 to 2003 in Jiashi--Bachu region. The horizontal pattern of the attenuation relationship is applicable to the earthquakes with magnitude 4.0～ 6.9, while the vertical pattern is applicable to earthquakes with magnitude 4.0～5.9.
