摘　　要：岩溶是工程建设中常见的地质现象。岩溶发育可能引发路基滑动、不均匀沉降、地表塌陷等地质灾害,严重影响高速公路的建设和运营。该文介绍了应用高密度电法在云南某高速公路进行路基勘察的实例,经钻孔验证,证明高密度电法能够有效查明路基岩溶发育及岩体破碎带情况,为后期工程设计及施工提供了重要的地质信息。Karst is a common geological phenomenon in engineering construction. The development of karst may lead to some geological disasters, such as the slip of subgrade, uneven settlement, ground col- lapse and so on. It seriously affects the highway construction and operation. This paper introduces an en- gineering example of the high density resistivity method applied to survey a highway subgrade in Yunnan. Verified by drilling ,it proves that the high density resistivity method can find out the situation of sub- grade karst development and rock fracture zone. It provides important geological information for later engi- neering design and construction.
