太阳山断裂带及周边地区多源遥感断层构造解译与分析

Interpretation and Analysis of Multi-Source Remote Sensing Fault Structure in Taiyangshan Fault Zone and Surrounding Areas

利用多源遥感数据及SBAS-InSAR技术,多尺度多角度开展太阳山断裂带及周边地区的断层遥感解译与对比分析工作。结果表明,研究区共发育6条主要断裂,其中太阳山断裂带构造地貌特征明显,由4条主干断裂组成,即岗市-河洑断裂、太阳山西侧断裂、肖伍铺断裂、仙峰峪断裂,主干断裂表现出线性陡坎、断层沟谷、湖泊边界、山体断错等异常地貌特征。SBAS-InSAR结果显示,研究区在2017-01~2019-10累积最大沉降量为62.59 mm,最大抬升量为59.42 mm,断裂控制着区域构造格架,影响地面抬升与沉降的分布格局,其中太阳山地区沉降与抬升的形变分布特征与构造带走向一致,可间接反映遥感解译的准确性。

We use multi-source remote sensing data and SBAS-InSAR technology to carry out fault remote sensing interpretation and comparative analysis of the Taiyangshan fault zone and surrounding areas from multi-scale and multi-angle.The results show that there are 6 major faults in the region.Among them,the Taiyangshan fault zone has obvious structural and geomorphological characteristics,consisting of 4 main faults,namely Gangshi-Hefu fault,the west side of Taiyangshan fault,Xiaowupu fault,and Xianfengyu fault.Several main faults show abnormal geomorphological features such as linear scarps,fault valleys,lake boundaries,and mountain faults.SBAS-InSAR results show that from January 2017 to October 2019,the area has a cumulative maximum settlement of 62.59 mm and a maximum uplift of 59.42 mm.The fault controls the regional structural framework and affects the distribution pattern of ground uplift and subsidence.The deformation distribution characteristics of subsidence and uplift in the Taiyangshan area are consistent with the direction of tectonic belt,which indirectly reflects the accuracy of remote sensing interpretation.
