| 摘 要： | 黑山峡大柳树坝址区主干活动断裂F201的规模及活动强度是影响坝址稳定的主要因素,通过分析坝址区基本断裂构造格局,阐述了F201断层活动对坝区内另一条主干断层F7(8)以及位于坝址上的数条次级断层的控制牵动效应.通过对F201现代活动规模及强度的讨论,认为该断层现代活动规模大于60 km以上.探槽显示,晚第四纪以来至少发生过7次震级古地震事件.其中大于7级的至少有4次.

| Abstract: | The size of the backbone FZOi of active faults and its active intensity are major factors which affecto stability of the damsite in daliushu damsite district of heishanxia gorge. By analyzing basic framework of fracture structure, expatiate the controlling and affecting of the activity of F201 fault on a series of secoridary faults and F7(8)which is another major fault. By discussing the size of the F201 of active faults and its active intensity, consider that the F201 fault is longer than 60Km. The frenche have revealed seven paleoearthquake events since late Pleistocene, at least four among the seven paleoearthquake events are greater than Ms≥7.0. |
