高密度电法与微动勘探在内蒙古某垃圾填埋场渗漏中的应用研究
Application of high-density electrical method and micro motion exploration in leakage of a landfill site in Inner Mongolia
摘要
Abstract
With the accelerated advancement of modern urban construction,environmental issues have become increasingly severe,and waste stands out as a key contributor to environmental pollution.To determine whether leachate from landfills leaks and contaminates groundwater resources and soil,it is essential to conduct relevant surveys of landfill sites.This study summarizes the resistivity and wave velocity characteristics of the main geological formations at a landfill site in Inner Mongolia,utilizing the high-density resistivity method and microtremor survey technique.The findings provide a technical basis for delineating the leachate pollution range,identifying the leachate migration direction,and defining the bottom boundary and distribution scope of the landfill.Geophysical survey results indicate that the bottom of the landfill in the study area is buried at a depth of 17-26 m,and two leakage points were identified within the landfill:one in the anti-seepage layer at the bottom of the landfill area and the other in the leachate regulation tank on the east side.Specifically,the anti-seepage layer at the bottom of the landfill area exhibits a relatively large leakage scale,with the impact extending 30 meters below the anti-seepage layer;however,the leakage has not penetrated the surrounding dam structure.Overall,this geophysical approach has effectively clarified the distribution scope and bottom burial depth of the landfill,delineated the leachate pollution range,and determined the pollutant migration direction,achieving favorable outcomes.It can serve as a technical support and reference for the ecological environment restoration and land development and utilization of similar landfill sites.关键词
