| 摘 要： | 本文深入分析了首都圈10个跨断层形变场地的流动观测资料,计算了断层水平滑动量.结果表明,首都圈断层形变反映的断层活动非常复杂.其中:NW走向的施庄断裂左旋滑动量与时间呈线性关系,在观测期内左旋滑动速率约为0.08 mm/a；NW走向的墙子路断裂观测期内以左旋滑动为主,但水平滑动量较施庄断裂小；NE走向的断层在观测期内的...

| Abstract: | Temporary cross-fault observation data in the past tens years in the capital region of China is studied in the paper.Distribution of fault strike-slips indicates the complexity of fault activities in the region.Left-lateral strike-slip of the Shizhuang fault,that trending northwest,is positively correlated with time.The mean left-lateral strike-slip rate on the fault is about 0.08 mm/a during the observing period.Left-lateral strike-slip of the Qiangzhilu fault,that is also trending northwest,is less than t... |
