中文摘要:渭河盆地是中国中部地区一个重要的新生代断陷盆地,也是一条重要的地震活动带,属于汾渭地震带的一部分。中国西部政治、经济、文化中心西安就位于其上。渭河盆地东南缘活动断裂非常发育、地震活动频繁,而且有1556年华县8级特大地震发生的背景。华县大地震是发生在高角度正断层上为数不多的强震之一,并且其发震构造目前还存在争议。华山山前断裂为正断型活动断裂,是研究正断型活动断裂与其灾害效应的典型实例。本论文通过对正断型断层活动与大地震及其灾害关系的研究,为评价西安等重要城市群的稳定性提供科学依据。

Activity of Main Faults since the Late Pleistocene and Related Geohazard Effects in Southeast of Weihe River Basin
Abstract:Weihe River Basin is not only one important Cenozoic rift basin, but also one significant seismically active belt belonged to Fenhe-Weihe seismic zone in central China. Xi’an city is located on Weihe River Basin, and it is the center of political, economic and cultural of western China. There are many active faults and earthquakes in Weihe River Basin. Huaxian county 8.0 earthquake in AD1556 is a key earthquake and occurred in the high angle normal faults of Weihe River Basin. The seismogenic structure of Huaxian earthquake is still controversial. Huashan piedmont fault is one high angle normal faults and maybe related to Huaxian earthquake. Thus, Huashan piedmont fault is a typical example of study relationship of normal fault and its disaster activities. This paper provide scientific basis for the stability evaluation of Xi'an city to study the relationship between fault activity and its earthquake and others disaster.
