太行山内断裂与地质灾害研究
Research on Faults and Geological Hazards in the Taihang Mountains
【摘要】 文章依据野外调查结果详细地总结了太行山内断裂的地质特征,对其形成机制和演化进程进行了分析。从区域大断裂,变质核杂岩,盆岭构造耦合和大河过境盆岭区四个维度,探讨了该断裂所处的地球动力学系统,并对该断裂可能出现的地质灾害进行了分析,得到一些认识,主要有(1)太行山内断裂是由一系列发育在古生代灰岩内的次级断层整体组合成的一条宽断裂带;(2)四个维度是一个有机的整体;(3)太行山内断裂不会产生地震地质灾害,但对通过该断裂的工程建筑可能产生危害。
【Abstract】 Based on field investigations, the geological characteristics of the Taihang Mountain Inner Fault are summarized. Its formation mechanism and evolutionary process are analyzed. The geodynamic system of this fault is explored from four perspectives: regional major faults, metamorphic core complexes, basin-range tectonic coupling, and large rivers traversing basin-range regions. Potential geological hazards associated with the fault are assessed. Key findings include:(1) The Taihang Mountain Inner Fault comprises a broad fracture zone formed by a series of secondary faults developed in Paleozoic limestone;(2) The four dimensions constitute an integrated system;(3) While the fault is unlikely to generate seismic hazards, it may pose risks to engineering constructions crossing the fault zone.
