摘　　要：高密度电法是一种直流电法勘探技术,具有测点密度高,信息量大,对探测对象不造成损伤,成果直观、准确、高效等特点而被广泛应用于岩溶勘察中。论述了其原理、技术方法并通过桥梁基础勘察和隧道工程两个应用实例,论述了高密度电法在桥基灰岩地层中圈定溶洞和在隧道内确认破碎带的应用,最后通过后期打钻证实高密度电法是岩溶勘探中一种可行有效的勘察方法。High-density electrical prospecting method is a direct current technology, with a measuring point density, amount of information, objects do not cause damage to the probe, the results intuitive, accurate and efficient characteristics which are widely used in Karst Survey. Discusses its principles, technical methods and through the bridge foundation investigation and tunneling two application examples, discusses the high-density electrical abutment limestone formations in the cave and the delineation of fracture zones recognized in the tunnel applications, and finally through the late drilling confirmed that high-density electrical karst exploration method a viable and effective investigation.
