随着地震地质工作的深入发展,考古地震地质已引起了国内外地震工作者的重视,因为它对研究全新世以来的新构造运动具有独特的意义。在考古地震地质工作中,对古地震遗迹,如地震断层、喷水冒砂、地震缝等的研究尤其重要。因为它真实地记录了古地震的踪迹,补充了历史文献记载的不足,对研究该地区强震活动规律具有重要意义。近年来,我们在研究北京平原全新世以来新构造运动工作中,重点对平原内全新统的岩相变化、古地貌特征等进行了野外调查,同时也注意了地层中古地震遗迹的探索。通过对十几处开挖土坑的详细观察,
With the deepening development of the seismo-geology work, archeological seismic geology has attracted the attention of earthquake workers both at home and abroad because it is of unique significance to the study of Neotectonics since the Holocene. In the work of archeology and seismic geology, it is especially important for the study of ancient earthquakes such as earthquake fault, water jet sand, seismic seam and so on. Because it truly recorded the traces of ancient earthquakes and added the shortcomings of historical records, it is of great significance to study the laws of strong earthquakes in the area. In recent years, during the study of neotectonic movement since the Holocene in the Beijing Plain, we focused on the field investigation of the lithofacies change and palaeogeomorphology of the Holocene in the plain. At the same time, we also paid attention to the exploration of the ancient earthquakes in the strata. Through a dozen excavation pit observation in detail,
