摘　　要：当前地表基质调查工作正在全国范围内开展,其中垂向结构特征调查是地表基质调查中的一项重要内容,而综合物探是垂向结构调查的主要探测手段。前期在梨树县黑土地地表基质调查工作中,开展了高密度电阻率法、微动勘探和地球物理测井等工作,揭露了地下0~50 m空间内基质层特征、厚度、地下空间展布情况,并结合已有钻孔资料和地质浅钻工作,对地表基质纵向空间展布及结构特征进行对比,取得了一定的实际效果。本文通过梨树县黑土地地表基质调查研究实例,对支撑地表基质垂向结构特征调查的物探工作进行梳理总结,分析综合物探手段在地表基质调查工作中的应用效果。Current ground substrate survey work is being conducted nationwide,with the investigation of vertical structural features being an important part of ground substrate survey.Comprehensive geophysical prospecting is the main detection method for vertical structure investigation.In the preliminary ground substrate survey of the black soil in Lishu county,Jilin province,high-density electrical method,microtremor exploration,and geophysical logging were carried out to detect and reveal the characteristics,thickness,and spatial distribution of the substrate layer within 0-50m underground space.Combined with existing borehole data and geological shallow drilling work,a comparison of the longitudinal spatial distribution and structural characteristics of the ground substrate was made,achieving certain practical results.This paper summarizes and analyzes the geophysical work supporting the investigation of vertical structural features of ground substrate through the research example of ground substrate survey of the black soil in Lishu county,Jilin province,and discusses the application effect of comprehensive geophysical methods in ground substrate survey work.
