摘要： 灰岩地区的工程地质勘察不仅要探明基岩的起伏，还必须查明区内的溶蚀带、溶洞、土洞等不良地质现象。由于这种不良地质情况出现的随机性较大，水平岩层变化显著，在水下情况用钻探成本高且难以达到理想效果。为探明水下岩溶发育与分布规律，尝试运用高密度电法进行探测，取得了预想的效果，可为类似工程提供参考。

Abstract: The geotechnical investigations in the karst terrains require not only to determine the variation the karstic rock surface, but also to real the development of the rock pinnacles, rock cavities in the rock mass as wells soil cavities at the soilbedrock interface. Due to the random occurrence of these adverse geological features, the drilling and rock coring cost will be excessively high, especially, if the drilling operation is under water. This paper presents the underwater highdensity resistivity method as a compensate method for the geotechnical investigations in the karst terrain.
