基于定点形变资料获取断裂浅层倾向和倾角的方法研究—以唐山台为例
Dizhen xuebao, 2018 本文利用唐山地震台1978—2016年跨断层定点形变资料探究唐山地震台所跨断层的浅层倾向和倾角。首先，对形变资料进行数字滤波处理，消除原始观测数据中的非构造信息；其次，对数据精度进行评价，得出1997—2016年滤波后的形变数据年累计残差普遍较小、精度较高；最后，采用精度较高的形变数据计算SE和NW两倾向不同倾角下基线与水准和的累计残差分布，进而获取断层的浅层倾向和倾角。结果显示，依据跨断层定点形变资料获得唐山地震台所跨断层的浅层倾向为SE，倾角为89°，该结果与前人探槽剖面中断层产状相一致 ...
