摘要： 结合具体工程实例,利用高密度电法获得了测区的二维高密度电阻率反演断面色谱图,通过对视电阻率二维成像图异常形态、高低阻等特征的分析,推断出覆盖层厚度、基覆界线,从而查明了滑坡体厚度及滑面起伏形态,为滑坡稳定性评价提供了依据。

Abstract: A successful landslide mitigation project requires an accurate characterization of the geotechnical and geological conditions of the sliding zone. This paper presents a case history of an application of highdensity resistivity method in the geotechnical investigation for a landslide mitigation project. The mechanisms of the highdensity resistivity method and this advantage as well as disadvantage are briefly introduced. The thickness of the overburden soils and the variation of the slip surface can be obtained from the twodimensional resistivity spectrum of throughout the cross sections.
