三高电法在高速公路岩溶勘探中的应用
APPLICATION OF "3-HIGHS" ELECTRICAL METHOD TO DETECTING INVESTIGATION OF HIGHWAYS' KARST CAVEMS
-
摘要: 本文介绍了三高电法在高速公路建设中,结合场地的地电特性进行岩溶、土洞勘查的异常特征,并通过两种测量装置获得了基本一致的异常形态,介绍的2个工程实例与钻探成果基本相吻合。Abstract: The text introduce "3-highs" electrical method to detecting Karst caverns and soil caverns,combining with the site of geoelectric model,and get a same result through 2 kind of scale-setting。The result of exploration is inosculate with drilling.
