在近年活动断裂研究成果基础之上 ,分析了鄂尔多斯地块周边断陷系 9次历史强震破裂的分段与活动构造之间的关系 .结果表明 ,在个别具有较大不确定性参数不参加统计情况下 ,这些强震地表破裂参数与活动构造之间表现出较好的相关性 ,反映出强震的破裂强度及地表破裂的分段与活动构造之间的内在联系 .同时 ,这些强震表现出特征型强震的稳定和非稳定的地表破裂边界 ,以及同一构造单元不同边界断裂存在的强震连续发生现象 .
Based on the research results of active faults in recent years, the relationship between the sub-section of the 9 historical strong earthquakes ruptures and the active tectonics in the Ordos block is analyzed. The results show that in the individual with large uncertainty parameters do not participate in the statistics , The correlation between the surface rupture parameters and the active tectonics of these strong earthquakes shows a good correlation, which reflects the rupture strength of strong earthquakes and the interrelationship between the subdivision of the surface rupture and the active tectonics.At the same time, the performance of these strong earthquakes The stable and unsteady surface rupture boundaries of the characteristic strong earthquakes and the continuous occurrence of strong earthquakes in different boundary faults of the same tectonic unit are presented.
