摘　　要：以淄博市活断层电成像探测的某些结果为例,阐述了电成像图像的地质解释和分析方法,探讨了用于城市活断层探测的仪器的输入阻抗范围以及数据处理和反演中需注意的问题。以控制张店—仁河断裂系的3个典型电成像剖面为实例,依此推断了隐伏断裂的位置,工程钻探验证了电成像结果的正确性,表明电成像方法完全可以在城市活断层探测中发挥作用。Exemplified by some results obtained from the electric imaging detection of active faults in Zibo City, this paper described the method for geological interpretation and analysis of images from the electric imaging technique, and studied the input impedance range of the instrument for urban active fault detection as well as some problems which deserve attention in data processing and inversion. With three typical electric imaging profiles that control the Zhangdian-Renhe fault system as examples, the authors inferred positions of the concealed faults and verified the correctness of electric imaging results through drilling. It is thus concluded that the electric imaging method can obviously play a very important role in the detection of urban active faults.
