山区是滑坡、泥石流等地质灾害的频发区,如何快速准确地查明这些灾害的空间特征对于评价及防治泥石流尤为重要。该文介绍了将高密度电阻率法应用到某地泥石流勘察中,确定了堆积体的厚度及基岩的分界面,得到了钻探的验证。结合当地的地质、水文条件分析了该区域的稳定性与泥石流等灾害可能发生的部位以及规模的大小。通过生成地质模型,形象直观地表现了该区域的地质情况,为当地建筑物的选址提供了可靠的地球物理依据,该文对泥石流的勘察以及防治工作具有一定的意义。
The mountainous area is a frequent area of geological disasters such as landslide and debris flow. How to quickly and accurately identify the spatial characteristics of these disasters is particularly important for evaluating and preventing debris flow. This paper introduces the application of high density resistivity method to the investigation of debris flow in a certain area, confirms the thickness of the deposit and the interface of bedrock, and obtains the drilling verification. Combined with the local geological and hydrological conditions, the stability of the area and the possible site and the size of the debris flow disaster are analyzed. By generating the geological model, the geological condition of the area is vividly represented, which provides a reliable geophysical basis for the site selection of local buildings. This article is of great significance to the exploration of debris flow and its prevention and control.
