简要介绍了高密度电阻率法的工作特点，应用该方法在南京长江第四大桥南接线中的某一段路面进行了探测，获得了测区内测线的视电阻率二维成像图，通过对视电阻率二维成像图异常形态、高低阻等特征的分析，推断出工区的基岩埋深以及地下岩溶、溶洞的分布范围、大小和埋深。经钻探资料证实，推断结果与实际情况基本吻合。

The article briefly introduced the characteristics of high-density resistivity method, and took the re- sults of the south past of the Fourth Nanjing Yangtze River Bridge in a section of the roadbed detection as an example, obtained some two-dimensional images of the apparent resistivity. Through the analysis of anomaly patterns in the two-dimensional images of the apparent resistivity, inferred the depth of bedrock and the distri- bution, the size and the depth of karst cave in the experiment site. The drilling data confirmed that the infer- ence were basically consistent with the actual situation.
