摘　　要：高密度电法是探测潜伏断层或隐伏断裂的主要方法,具有工作效率高、探测精度高等特点,以柳州市立冲沟生活垃圾填埋场为例,探讨高密度电法在探测隐伏断裂或溶洞中的应用。首先,采用Wenner、Dipole-Dipole、Schlumberger三种装置进行数据采集,GPS测高,然后进行二维反演,得出地下电性分布情况,最后进行钻探验证。结果显示,工作区地层大多为三层结构,电阻率的横向连续性较好,与高密度反演结论一致。此次工作查明了立冲沟填埋场地下的地质情况,为高密度电法在探测潜伏断层或隐伏断裂中的应用提供了例证。High density electric method is the main method to detect for concealed faults,which has the characteristics of high working efficiency and high detection precision.For an example of Lichonggou waste landfill site in Liuzhou City,this paper has studied the application of high density electric method to detect for the concealed fault and karst cave.Firstly,Wenner,Dipole—Dipole and Schlumberger devices are used for data collection,GPS for height measurement,and then two-dimensional inversion is conducted to obtain the distribution of underground electrical properties.Finally,the drilling verification is carried out.The result shows that most of the stratum structure in the working area are three-layered,and the resistivity has a good horizontal continuity,which is consistent with the high density inversion conclusion.This work has found out the geological condition under the Lichonggou waste landfill site and has provided an example for the application of high density electric method to detect for the concealed faults.
