该文以西藏某尾矿库地基勘察为例,介绍了在高原灰岩发育地区如何利用高密度电法结合钻探对库区岩溶进行探测。验证的结果,说明了高密度电法在查明岩溶分布的位置、形态、规模以及填充物性质等方面具有独特的优势,是一种有效的物探方法。
In this paper, taking a ground investigation of a certain tailings reservoir in Tibet as an example, how to detect the karst in the reservoir area by using high density electric method and drilling in the limestone development area of the plateau is introduced. The verification results show that the high-density electrical method is an effective geophysical method which has unique advantages in identifying the location, shape, scale and properties of the karst distribution.
