摘    要:千佛山断裂是济南市的一条重要隐伏断裂,研究该断裂的具体位置,断裂展布以及断裂的活动性具有重要意义。本文利用遥感技术、地球物理勘探(CT)、地质勘察等综合地质与地球物理探测手段,对该断裂地形地貌特征、地质构造特点、地层年代进行研究,分析其地震活动性。结果表明该断层中更新世早中期以来没有明显的活动证据,该断层的活动年代为早更新世-中更新世早期。千佛山断裂的运动性质以张性正断层为主,兼有左旋走滑运动的特点。从断层的几何结构分析,中更新世早中期以前断层经历了多期活动。

关 键 词:千佛山断裂  综合地球物理探测  地震活动性

Abstract:Fracture of Mount Qianfo is an important hidden fracture. To analyze the exact position of fracture, the habitat of rifts and the seismicity of fracture is of great significance. This thesis makes a comprehensive detection and analysis of this fracture with the techniques and strategies of Remote Sensing, Geophysical Detection, Geologic Structure and Engineering Geological Investigation, offers this fracture a precise localization and provides ananalysis for the seismicity property of fracture. This thesis also gives measurement result according to the tectonic characteristics of the fault, the geological features, fault materials and the overlying quaternary strata age, and makes sure that this fracture is the active fault in the early Pleistocene to Pleistocene. And there’s no significant sign of activity from the Pleistocene to now. The main movement property of fracture of Mont Qianfo is extensional normal fault, and also includes the left-lateral strike-slip motion. From the aspect of the relationships between the structures of the fault surface, the fracture had experienced polystage activities before the early and mid period of Pleistocene.
Keywords:fracture of mount Qianfo  comprehensive geophysical detection  seismicity of fracture
