摘　　要：地质勘探的精度是影响非正规垃圾填埋场环境综合调查成果可靠性的重要因素之一。选择某非正规垃圾填埋场,采用钻井—高密度电阻率法进行联合勘探,实施754个高密度电法测点,12口参数井和航测工作。基于填埋层、填埋基底二元分析方法以及模糊数学理论解释分析了4层填埋物、基底和渗滤液的分布特征。建立填埋场三维地质模型,分析了环境地质要素的空间展布特征。钻孔验证结果与方法适用性评价表明,钻井—高密度电阻率法联合勘探可应用于非正规垃圾填埋场调查,以获取符合场地特征的可靠地质成果。Geological exploration accuracy is a significant factor in the reliability of the comprehensive environmental survey outcomes of informal landfill sites.This study conducted drilling-high-density resistivity joint exploration of an informal landfill site using 754 high-density resistivity measurement points,12 parameter wells,and aerial surveys.Based on the binary analysis method of landfill layers and base,as well as the fuzzy mathematics theory,this study analyzed and interpreted the distribution characteristics of four layers of landfills,base,and leachate.Furthermore,this study established a 3D geological model of the landfill site and analyzed the spatial distri-bution of environmental geological elements.The drilling-derived verification results and the applicability evaluation demonstrate that the drilling-high-density resistivity joint exploration can be used to investigate informal landfill sites to obtain reliable geological results con-sistent with site characteristics.
