摘　　要：对于碳酸盐岩地层中的多层岩溶、溶洞洞高较小或顺层岩溶,直接从高密度电阻率拟断面图和反演电阻率断面图上难以将其区分。通过从高密度电法数据中抽取电测深曲线,对一系列测点的电测深视电阻率曲线进行解释,同时结合其视电阻率拟断面图和反演电阻率断面图作出推断,能有效地将上述岩溶进行区分。在湖南省某高速公路跨线桥墩台桩基工程基础勘探中的实践表明,使用该方法可获得较好的地质解释效果。For multilayer karst, the caves are rather small or the karst is developed along the bedding, and hence it is difficult to dis-tinguish them directly from the cross-sectional view of the high-density resistivity method. By utilizing sounding curves extracted from high density electrical data and analyzing synthesized sounding curves as well as a cross-sectional view, different kinds of karst can be effectively distinguished. Engineering practice shows that the extraction of sounding curves from the data of high-density resistivity meth-od for interpration can result in fairly good geological interpretation results.
