摘要： 随着科技的发展，物探方法被越来越多应用在岩溶勘察上，物探常用的测试方法有高密度电法、瞬态面波法、电磁波CT探测、地质雷达等。鉴于岩溶发育的复杂性，单一物探方法难以充分满足勘察要求，为了克服单一手段的局限性，通过多种物探手段的综合运用，有效解决这些不足，结合传统钻探互为补充验证，成为目前岩溶勘察的可靠选项。通过地质钻孔揭露地层与物探成果相互印证，结果基本相符，充分证实了多种物探手段结合的科学性、高效性。在复杂的岩溶地质环境下，采取综合物探手段，可减少盲目按照规范布孔造成的疏漏。

Abstract: With the development of science and technology, a variety of geophysical methods are increasingly used in the karst explorations. The commonly used test methods of geophysical exploration include high-density electrical method, transient surface wave method, electromagnetic wave CT detection and geological radar, etc. In view of the complexity of the karst terrain investigations, a single geophysical method is difficult to fully meet the exploration requirements. To overcome the limitations of a single method, the comprehensive application of multiple geophysical methods can effectively resolve this problem. Combined with the complementary verification of the traditional drilling, it has become a reliable option for the current karst investigation methods.
