高密度电阻率三维可视化成像技术在垃圾填埋场环境修复治理中的应用研究

Research on the Application of 3D Visualization Imaging Technology of High Density Resistivity in Environmental Remediation of Landfill

在我国城镇化快速进程中,垃圾填埋场数量激增,伴随而来的渗漏污染事件频频发生,对人们生存环境造成了严重的威胁,制约了城市发展。本次研究通过在四川省某垃圾填埋场开展的高密度电阻率法调查,归纳总结出了垃圾场主断面上电阻率异常特征,再结合地质、钻孔资料综合解释验证,应用三维可视化分析技术,查明了垃圾场原址边界范围和垃圾场底部地质情况,其包括:岩石裂隙位置、含水破碎带,排查出了有建设施工隐患的不稳定地质体,为垃圾填埋场的环境修复治理及土地恢复开发再利用提供了可靠的地球物理依据。

In the rapid process of urbanization in our country,the number of landfill is increasing rapidly,and the leakage pollution events that come along with it happen frequently,which has caused serious threat to people's living environment and restricted the development of the city.Based on the investigation of high-density resistivity method in a landfill site in Sichuan Province,this paper summarizes the abnormal characteristics of resistivity on the main section of the landfill site.Combined with the comprehensive interpretation and verification of geological and drilling data,the three-dimensional visual analysis technology is applied to find out the boundary scope of the original site and the geological situation of the bottom of the landfill site,including the location of rock fissures and water bearing fracture zone.The unstable geological body with construction hidden danger has been found out,which provides reliable geophysical basis for environmental remediation and land recovery and development and reuse of landfill.
