高密度电阻率法在某地区泥石流勘察中的应用与研究

Application and Research of High-density Resistance Method in Debris Flows Exploration

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。

Mountainous is the geological disaster-prone area,such as the landslides,debris flows and so on. How to accurately identify the spatial characteristics of these disasters is particularly important for its prevention. In this paper,high-density resistivity method is used to debris flows exploration to determine the depth of the slide and the bedrock interface,and verify the accuracy of the information by drilling.Combined with the local geology and hydrology,this paper analyzed the stability of the region,and forecasted the occurring parts and the size of the debris flows. By generating the geological model,the geology of the region is performed intuitively. The model provides a reliable geophysical basis for the siting of local buildings. This paper has certain significance for the investigation and prevention of the debris flows.
