| 摘 要： | 史料记载和涵洞路槽开挖表明,在距今9110a以来渭河断裂带窑店—张家湾段曾发生1次历史地震、3次古地震事件。其中历史地震即第Ⅳ期地震的发震时间在公元1487—1568年之间;事件Ⅰ为距今(9110±90)a,事件Ⅱ和事件Ⅲ距今时间不详。第Ⅰ,Ⅱ,Ⅲ期地震事件的同震垂直位移量分别为0.5,0.5,0.2m。涵洞路槽开挖也表明,渭河断裂窑店—张家湾段为全新世活动断裂

| Abstract: | Weihe Fault is an important buried fault in Weihe basin.The predecessors have investigated the location and activity of the fault from various points of view,but up to now,the level of researches on the precise location and activity for the fault is still very low.There are few strata profiles of late Pleistocene which are found to be offset by the fault zone.Especially,it is still unknown whether the Weihe Fault was active in Holocene and there were paleoseismic events occurring on it.It is indicated from |
