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。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.
