摘　　要：高密度电法是工程地质勘察中应用较多的地表物探技术之一,其对含水性地质病害具有较高的预报精度。文章依托岗头山隧道和叙岭关隧道项目,介绍了富水性区域病害、充填粘土型溶洞病害和断层破碎带等三类典型工程实例的成功经验,并且对漏测、检测结果的多解性和异常信息缺失等常见应用问题及其应对方法进行了总结分析。As a kind of popular geophysical exploration technique,the high density resistivity method is widely applied in engineering geological investigation,which is extremely sensitive to predict geological defects in water-bearing areas.Taking its application in Gangtoushan tunnel and Xulingguan tunnel for example,three successful cases are comprehensively introduced,including defects in water-rich region,karst caves filled with clay and fault-fractured zones.Then the common problems like missing checking,non-uniqueness of inspecting results and lack of anomalous information are summarized and analyzed,with the corresponding solutions to them put forward.
