通过对首都圈地区不同时期的18条深地震测深(DSS)测线资料的重新统一处理,形成采样网格密度为0.25°×0.25°×(2~5)km的速度网格化数字地壳;通过对三维数据的可视化,得到了首都圈地壳不同走向、不同圈层的截面图像;从不同的视角、不同的方面探讨了控制首都圈地壳的北部燕山隆起、西南部太行隆起和东南部裂陷盆地等三大地质单元的构造特征以及接触带张家口-渤海断陷带的构造性质,进一步研究首都圈地壳内部结构构造与灾害性地震的孕发机制的关系. Through the reunification of 18 deep seismic sounding (DSS) survey data in different periods in the metropolitan area, a velocity gridded digital crust with a sampling grid density of 0.25 ° × 0.25 ° × (2 ~ 5) km was formed Through the visualization of three-dimensional data, the cross-section images of different directions and different layers of the crust in the capital are obtained. From different perspectives and different aspects, the control of the Yanshan uplift in the north of the capital capitals, the Taihang uplift in the southwest and the southeast The tectonic features of the three major geological units, the tectonic features of the Zhangjiakou-Bohai fault zone in the contact belt, and the relationship between the structural structure of the crust in the capital and the pregnancy-induced mechanism of disastrous earthquakes.
