高密度电阻率法在雄安新区浅表古河道精细化探测中的应用研究

    Application of the high-density resistivity method in detailed exploration of superficial paleochannels in Xiong'an New Area

    • 摘要: 为实现雄安新区浅表古河道的精细化探测,在遥感工作的基础上,在研究区开展了两条高密度电阻率法剖面探测,经钻孔验证,利用高密度电阻率法确定的古河道分布范围具有较高的准确度,探明区内古河道具有“弯曲”、“迂回”和“辫状”的平面分布特征,实现了精细化探测的目的,取得了良好的应用效果,为探测和研究浅表古河道提供了新思路,为类似地质条件区域调查古河道方法选择提供了借鉴和参考。

       

      Abstract: To explore in detail superficial paleochannels in Xiong'an New Area,this study investigated two profiles in the study area using the high-density resistivity method based on previous remote sensing.The interpretation results were verified through drilling.The distribution range of the paleochannels that was delineated using the high-density resistivity method was more accurate than that obtained from remote sensing.This study determined that the superficial paleochannels in the study area exhibit curved,tortuous,and braided planar distribution,achieving excellent application performance in the detailed exploration of superficial paleochannels.This study provided a new idea for future exploration and study of superficial paleochannels and can be used as a reference for the selection of methods used to investigate paleochannels in similar geological conditions.
