摘　　要：基于应用地球物理电法勘探原理,利用高密度电阻率法对山西省万家寨引黄入晋工程北干线2#隧洞倒虹吸输水线路的隐伏断层进行了勘察解释。经验证,物探解释深度与钻探揭露断层面深度相对误差为5.9%-6.3%,满足勘探精度要求。物探解释时,数据处理应按照一定的原则进行,避免畸变点的影响。应利用电阻率断面反演、视电阻率等值线和不同深度电剖面进行综合分析,才能达到准确解释。Based on geophysical electrical prospecting principle, high-density resistivity method was used to survey and interpretation for buried fault located on inverted siphon water diversion route of 2# tunnel in the north trunk of the Wanjiazhai Yellow River Diversion Project in Shanxi province. The relative error between geophysical interpretation depth and fault plane depth revealed by drilling is verified to be 5.9 -6.3%, and could satisfy the exploration precision requirement. Data should be treated according to certain principles in geophysical interpretation to avoid the influence of distortion point. Accurate interpretation could be achieved by comprehensive analysis of pseudosection inversion,apparent resistivity isoline and electric profile with different depth.
