高密度电法在黄土塬地区断层探测中的应用

Application of High-Density Electrical Method in Fault Detection in Loess Plateau Area

摘要: 高密度电法作为一种先进的地球物理勘探方法，具有高效率、高分辨率的特点，在断层探测中发挥着重要作用。考虑到已有反射地震勘探资料显示在该地区探测效果较差，故而本次物探工作采用高密度电阻率法。文章以某开发区断层探测具体应用为实例，详细介绍了高密度电法的基本原理、工作方法，并结合钻探成果佐证。研究表明，高密度电法能够有效识别断层位置、产状和性质，为工程地质勘察和地质灾害防治提供可靠依据。分析钻孔取心结果可知物探剖面成果准确，研究成果可为城市地下断层探测研究工作提供参考。

Abstract: High density electrical method, as an advanced geophysical exploration method, has the characteristics of high efficiency and high resolution, and plays an important role in fault detection. Considering that the existing reflection seismic exploration data shows poor detection performance in this area, high-density resistivity method is adopted for this geophysical exploration work. The article takes the specific application of fault detection in a certain development zone as an example, and provides a detailed introduction to the basic principles and working methods of high-density electrical methods, supported by drilling results. Research has shown that high-density electrical methods can effectively identify the location, orientation, and properties of faults, providing reliable basis for engineering geological exploration and geological disaster prevention. The analysis of drilling and coring results shows that the geophysical profile results are accurate, and the research results can provide reference for urban underground fault detection research.
