应用高密度电法探测北京南口-孙河隐伏断裂

Detecting Nankou-Sunhe Buried Faulty by High Density Resistivity Method

举例说明了高密度电法在北京南口-孙河活隐伏活动断层勘测中的应用,展现高密度电法在断层定位中的广阔应用前景。简单介绍了高密度电法的基本原理。视电阻率异常剖面揭示南口-孙河断裂为正断层,北东盘上升,南西盘下降,推测断裂倾角60°～68°。视电阻率异常剖面与钻孔资料对应较好,并与钻探资料分析的断裂活动特性基本吻合。

By exampling and explaining the application of high density electrical method in Nankou-Sunhe active buried fault project,we exhibited the wide application prospect of high density electrical method in the fault localization.And we introduced briefly the basic principle of high density electrical method.We showed that the Nankou-Sunhe active buried fault is a normal fault;its northeast wall rises and the southwest wall drops.The speculated dip of the fault is 60°～68°.And the characteristics of the active fault from borehole data are basically consistent with the resistivity data.
