Shallow Structure and Quaternary Activity Characteristics of Handong Fault

摘要: 邯东断裂为太行山山前断裂以东的一条隐伏断裂，是华北平原坳陷区内邯郸凹陷的东界断裂，位于邯郸东部新区规划建设范围内。研究其空间分布特征和活动性对于地震危险性评价及城区重大工程项目选址具有重要意义。本文采用浅层地震勘探、钻孔联合剖面探测和年代学测试方法，对邯东断裂的展布特征及第四纪活动性进行系统研究，共布设跨断裂浅层地震勘探测线6条、钻孔联合地质剖面3条。综合分析表明，邯东断裂为一条近NNE-SSE走向的高角度正断层，倾向W，视倾角约50°~75°。断裂上断点埋深南浅北深，最新活动时代为中更新世晚期。中更新世早期，南段与北段相比较为活跃。Abstract: The Handan fault is a concealed fault located east of the Taihang Mountain Piedmont Fault, serving as the eastern boundary of the Handan Depression in the North China Plain Depression. This fault lies within the planning and construction zone of the Eastern Handan New Area. Studying the spatial distribution characteristics and activity of the Handan fault is crucial for earthquake risk assessment and the site selection of major regional engineering projects. This paper systematically analyzes the distribution characteristics and Quaternary activities of the Handan fault by using shallow seismic exploration, a drilling joint profiling method, and chronology. Six shallow seismic exploration lines and three drilling joint geological sections across the fault have been conducted. Comprehensive analysis reveals that the Handan fault is a NNE-SSE trending normal fault with a westward dip and an apparent dip angle of about 50° to 75°. The upper breakpoint of the fault is shallow in the south and deep in the north, with the latest active period occurring in the late Middle Pleistocene. In the early Middle Pleistocene, the southern segment was more active than the northern segment.
