超高密度电法在查明地铁车站岩溶中的应用

摘要

Through an engineering example,this paper introduces the thought and working procedure of super-high density resistivity method used in krast detection during the subway stations investigation.According to the anomaly characteristic of karst,the geophysical exploration results are analysed and explained.Combined with the drilling data,the karst caves and development range of fissures are divided clearly and accurately,and it provides reliable geological data for the following works.%该文通过工程实例,介绍了利用超高密度电法对地铁勘察中的岩溶进行探测的思路和工作方法,根据岩溶异常特征判别,对物探成果进行了分析解释,并结合钻探资料,清晰、准确地把溶洞和裂隙发育范围划分出来,为后续工程提供了可靠的地质资料.
