摘要: 以摩岗岭滑坡勘查为例，通过高密电法二维剖面反演，能够清晰地反映滑坡体各层位及其相应的深度，有效地确定滑带的深度及厚度，确定基岩面埋深，指导钻探的位置及深度。通过三维高密度电阻率法反演，可对不同（二维）切片进行分析，有效了解整个滑坡体的基本特征。通过对低阻异常体的立体显示，更宏观地表达滑坡体的三维特征，可以对滑坡体规模进行预测。Abstract: Landslide is one of the common geological disasters, how to accurately detect the depth of sliding surface, to determine scale landslides and geological disaster evaluation is very important. Hill landslide survey, for example, this paper takes the hills, through inversion, the high-density electrical method two-dimensional profile can clearly reflect the depth of the landslide’s horizon and its corresponding to effectively determine the depth and thickness of the sliding zone, to determine the embedded depth of bedrock surface; The location and depth of drilling. Through three dimensional inversion, the high density resistivity method can analyze the different(two-dimensional) slice, effective understanding of the basic characteristics of the whole landslide; Based on the low resistance of abnormal body stereo display, more three-dimensional characteristics of the macroscopic representation of landslide, the landslide scale can be predicted.
