摘　　要：利用山东数字地震台网二年多的地震记录资料,根据陈培善等用地震发生的断裂力学模式和震源谱理论,导出的震源处峰值加速度与构造环境剪应力值的关系,计算了山东内陆及附近海域发生的46次中小地震构造环境剪应力值,并对应力场的分布状况和时空变化进行了分析。Based on earthquake rupture model and seismic source theory by Chen, using the digital observation data from the Digital Seismic Network of Shandong Province, the relation between peak ground acceleration and tectonic ambient stress value has been derived. We have calculated the stress values for 46 earthquakes occurred in Shandong area, and analyzed the time and space distribution characteristics of stress filed.

关 键 词：峰值加速度 环境剪应力值
