岩溶地区溶隙裂隙型渗漏探测技术

Technology applied in prospecting solution fissure leakage in karst area

以广西某水库土石坝渗漏探测工作为例,针对岩溶地区大坝渗漏分散、小规模等特点,结合声呐探测、高密度电法、浅层地震法、自然电场法、电磁波CT等多种物探方法,提出了一套针对性强、适宜性好、准确性高的探测技术和方法,为解决岩溶地区大坝溶隙裂隙型渗漏提供了技术保障,为岩溶地区水库大坝除险加固提供了依据。

Taking the seepage prospecting for an earth-rock dam in Guangxi as example,according to the character⁃istics of main dam leakage in karst areas are scattered and small-scale,multiple geophysical prospecting methods including sonar detection,high-density electrical method,shallow seismic method,natural electric field method and electromagnetic wave CT etc.were integrated to put forward a set of prospecting technology and methods with strong pertinence,good suitability and high accuracy,which provided technical guarantee for solving the dam solution fis⁃sure leakage problem and basis for reservoir dam reinforcement in karst area.
