北京黄庄-高丽营断层、八宝山断层现今活动追踪研究

综合分析了控制黄庄—高丽营断层、八宝山断层活动性的形变、重力及地磁资料，认为断层的活动以永定河断层与良乡断层之间最为显著；其活动与强震的发生密切相关；断层所在地段是地震活动引起应力场变化的敏感地区。是大同及张北地震后应力转移集中的地区。转移集中的部分应力可能以断层蠕动的形式得到缓慢释放。

Tracing study of fault activity of the Beijing Huangzhuang-Gaoliying fault and Babaoshan fault in recent time

In this paper we have analyzed the data of deformation, gravity and geomagnetism that control activity of Huangzhuang-Gaoliying fault and Babaoshan fault. It is considered that the fault between Yongdinghe and Liangxiang is the most active one. This fault activity is closely related to the occurrence of strong earthquakes. The region, where Huangzhuang-Gaoliying fault and Babaoshan fault are located, is the sensitive area of stress field variation resulted from seismic activity. It is the region of stress migration and concentration after Datong earthquake and Zhangbei earthquake. The migrated and concentrated partial stress is possibly released slowly in the form of fault creep.
