摘　　要：探讨了不同类型隐伏断层的电性特征及其在浅层电法测试中可能的表现形式,并通过实例阐述了浅层电法探测隐伏断层的步骤及异常识别方法。研究表明浅层电法对某些类型的隐伏断层的探测是有效的,但先验知识非常重要,对于隐伏断层的探测效果与解译起关键作用。The electrical characteristics of buried fault in different environment, and the curve shape of resistivity composite profile for different kinds of fault. The process of buried fault prospecting by superficial direct-current electrical method is illustrated by real some cases. The results show that superficial direct-current electrical method is valid to the detecting of some kind of buried fault but the prior knowledge is very important and is the key to the efficiency of prospecting and the interpretation of result.
