| 为了避免单一物探方法在地质反演解释中存在的多解性弊端，本文介绍了以电成像法为主、浅层地震反射波法为辅的综合物探方法对隐伏断层进行探测的应用实例，并分别对两种物探方法的探测成果进行了深入分析、对比解释。经钻孔验证表明，电成像与浅层地震联合方法在浅覆盖区隐伏断层探测中具有精确、可靠、经济的优势，该方法具有较强的应用价值。 |

| Data of single geophysical methods often have multiple solutions in geological inversion interpretation. Collocated geophysical techniques can help solve this problem. This paper presents an application case of a comprehensive geophysical exploration which combines the resistivity tomography and the shallow seismic reflection to detect concealed faults. First, the resistivity tomography is conducted to identify the fault location, and then the shallow seismic reflection method is used to delineate its?attitude, characters,?position?and?displacement. The results of resistivity tomography can enhance the reliability of shallow seismic reflection survey. At the same time, the shallow seismic survey can improve the accuracy of concealed fault detection, so the comparative?analysis of results from the two methods permits more reliable and precise detection to hidden faults. Drilling data prove that the collocated resistivity tomography and the shallow seismic method have an advantage in accuracy, reliability and economy in detecting concealed faults in areas with thin covers. This approach has a great practical value. |
