高密度电法在岩溶地区溶洞勘查中的应用

Application of High-density Electrical Method to Exploration of Karst Caves

简要介绍了高密度电法在岩溶发育区进行大型岩溶溶洞探测的应用。根据已知溶洞上方布置的试验剖面结果得知,溶洞未被填充实,为高阻异常反映;通过对二维反演模型的异常特征分析,推断勘查区溶洞的分布范围、地质走向、大小和埋深。为后期大型溶洞开发及合理利用,提供了重要参考价值及指导性意义。

This paper introduces briefly the application of high-density electrical method to the detection of karst cave in large karst areas. According to the results of the test section arranged above the known karst cave, it is found that the karst cave is not filled and is the reflection of high resistivity anomaly. Through the analysis of the anomalous characteristics of the two -dimensional inversion model, the distribution rangegeology trend, size and depth of karst cave are inferred in the exploration areas, which provides an important reference value and guiding significance for the later large -scale cave development and rationaluse.
