摘　　要：利用高密度电法仪,采用施龙贝格装置对沁河大堤某合同段进行了电阻率CT探测。坝体内的破碎、沉降、裂缝以及洞穴等隐患部位有均匀清晰的反映。江河大坝是其流域地区人民生命财产安全的保障,是关系到国泰民安的大事。对沁河大堤的隐患探测具有重要价值和意义。以电阻率成像法的运用,使得解释工作更加方便与直观,并具有较好的实用性、有效性和可操作性。Using the high density electrical method meter, used Schlumberger array to install to the Qinhe river main dike some contract section has carried on the electronic resistivity CT survey. In dam stave, subsidence, crack as well as cavern and so on hidden danger spot even clear reflections. The rivers and streams dam is its basin area people personal safety and property safeguard, is relates the peaceful country and safe people the important matter. Has the important value and the significance to the Qinhe river main dike＇s hidden danger survey. By the electronic resistivity image formation＇s method utilization, causes the explanation work to be more convenient and to be direct-viewing, and has the good usability, the validity and the feasibility.
