【摘要】 根据云南地区的实测强震加速度资料 ,采用回归分析法研究了云南地区的地面水平、垂直峰值加速度衰减规律。共选取云南地区加速度记录 2 4 0条 ,进行了加速度衰减规律的统计 ,并把得到的结果与前人的结果进行比较分析 ,提出更适合云南地区地震地质特征的加速度衰减规律。更多还原

【Abstract】 Based on the observed data of strong motion acceleration in Yunnan region,the surface attenuation pattern at horizontal and vertical peak acceleration is studied by regressive analyzing method.240 acceleration recordings in Yunnan region are selected to do statistics of acceleration attenuation pattern.Comparing the results with the ones previously made by others,an acceleration attenuation pattern,which is more suitable to the seismo-geological characteristics in Yunnan region,is put forward in this paper.更多还原
