摘要
本文利用短期临时台网对林县微(小)震活动监测的资料,经过统计处理求出微(小)震综合断层面解,推测林县地区现代应力场的状况:主压应力(P)轴方向为78°,仰角49°;主张应力(T)轴方向为330°,仰角14°。最后简要讨论了林县地区应力场与华北地区区域应力场的关系。
Based on the microseismic data in Lin-xian region observed by temporary station network, the Composite fault plane solution of micro-earthquakes has been obtained with stereographic projection of first p-wave motion。The present stress field inferred in Lin-xian region is as follows: the direction of maximum pricipal stress is of NE78°, and its angle of elevation is of 49°; the direction of minimum principal stress is of NW330°, and its angle of elevation is of 14°. In addition, the relationship between Lin-xian region and North China stress fields has been briefly discussed.
