高密度电法在铁路沿线岩溶勘测中的应用

Application of High Density Electrical Method in Karst Survey along the Railway

高密度电法数据采集密度大、成本低、施工操作效率高,用此法来查明铁路沿线岩溶分布特征,不失为一种快速、简便的方法。通过运用高密度电法对某铁路线改扩建岩溶路基进行勘测,并与钻孔地质断面进行比较分析。结果表明,勘测结果与钻探资料比较吻合。

The high density electrical method has the advantages of large data collection density, low cost and high efficiency of operation. Using ithis method to identify karst distribution along the railway is a quick and simple way. Through survey to extension karst subgrade of a railway with high density electrical method, conduct comparative analysis combined with the drilling geological section. The results showed that the survey results are consistent with the drilling data.
