高密度电法与钻探法点面结合综合探查场地填埋层空间分布特征

当各类垃圾埋入地下后，垃圾渗滤液会逐渐由包气带渗入土壤中，对土壤环境造成一定影响。鉴于上部填埋层与下部原状土层之间会存在显著的物性差异，高密度电法定性探查精度有限，钻探勘察耗时耗力且成本高，两种方法优劣互补，对综合查明填埋层的空间分布特征具有实际应用意义。主要利用高密度电法无损探测和钻探法重点勘察的点面结合综合探查了某填埋场，查明了场地的地层结构及填埋层的空间展布情况，借助Volxer软件绘制了高密度电法反演形体渲染成果图，同时采用GMS软件构建了三维填埋层实体可视化模型，对比分析了两种手段的应用成果，为填埋场污染治理修复与风险管控提供了理论依据。

Comprehensive Exploration of the Spatial Distribution Characteristics of a Landfill Layer by High Density Electrical and Drilling Method

When all kinds of garbage are buried in the ground, the landfill leachate will gradually infiltrate into the soil from the aeration zone, causing a certain impact on the soil environment. In view of the significant physical property difference between the upper landfill layer and lower undisturbed soil layer, the high-density electrical method is of limited precision, and the drilling survey is time-consuming, labor-consuming and costly, so complementing the advantages and disadvantages of the two methods has practical application significance for comprehensively identifying the spatial distribution characteristics of landfill layer. In this study, a landfill was explored by the combination of high-density electrical method and drilling method, and the stratum structure of the site and the spatial distribution of the landfill layer were found out, and the three-dimensional stratum solid model was constructed, and the spatial distribution of the landfill layer was determined with the Volxer software drawing the rendering results of high-density electrical inversion and constructing the 3D solid visualization model of landfill by GMS software, and analyzing the application results of the two methods, which provided a theoretical basis for landfill pollution control and risk control.
