福建及邻近海域地区环境剪应力场的研究

Research on environment shear stress field in Fujian and its vicinity sea area

根据陈培善等(1993年)导出的峰值加速度、峰值速度和峰值位移与环境剪应力场的关系。利用福建省台网数字地震记录的福建5个区域(安溪、莆田、厦门海域、惠安海域、晋江海域)101个2~4级中小地震研究了福建及邻近海域地区构造环境应力场的变化,并推测出这些地区的地震危害性。分析各区地震活动的环境剪应力场随着时间、空间的变化,显示整个环境应力强度的空间分布并不十分突出。

According to the relationship between peak acceleration,velocity and displacement and environment shear stress field from Chen Peishan(1993),the paper using 101 Ml2～4 earthquakes occurred in five regions to study change of structure environment stress field and concluded the seismic risk in these area.
