西秦岭北缘断裂带的位移累积滑动亏损特征及其破裂分段性研究

根据西秦岭北缘断裂带的水平位移分组特征，定量计算了断裂端部和不连续部位的位移累积滑动亏损率，同时结合断裂带上的障碍体规模，滑动速率的差异，历史地震及古地震特征等，对断裂带进行了破裂分段性研究，结果表明，西秦岭北缘断裂带可以划分为鸳凤断裂，漳县断裂，锅麻滩断裂３条一级破裂段，６条二级破裂段。

RESEARCH ON THE FEATURES OF DISPLACEMENT CUMULATIVE SLIP DEFICITS AND SEGMENTATION IN THE NORTHERN MARGIN FAULT ZONE OF THE WESTERN QUINLING

According to the features of displacement cumulative slip deficits in the northern margin of the Western Qinling and considering the scale of barriers, the difference of slip rates and the features of historical earthquakes and palaeoearthquakes et al, we discussed the rupture segmentation of this fault zone. The result indicate that the northern margin fault zone of the Western Qinling can be divided into Yuanfeng fault, Zhangxian fault and Guomatan fault in first grade and 6 in second grade.
