综合物探技术在垃圾填埋场渗漏探测中的应用研究

Application of Integrated Geophysical Prospecting Technology in the Landfill Leakage Detection

随着我国垃圾填埋场数量的快速增长,填埋场的渗漏问题严重危害所在地区生活环境和人民的生命安全。由于单一物探方法的局限性,无法实现独自解决垃圾填埋场渗漏问题。因此,本文在分析常用的几种物探方法优缺点的基础上,综合采用充电法、高密度电阻率法和瞬态面波勘探法对坝体渗漏问题进行探测研究,多种物探技术互相结合、互相验证、互相补充,在垃圾填埋场垃圾挡坝渗漏通道探测中取得了较好的效果,为垃圾填埋场相似渗漏问题的地球物理方法选取提供一定的借鉴。

With the rapid growth of landfill sites in China,the leakage of landfill sites seriously endangers the regional living environment and local people's health.Due to the limitations of a single geophysical method,it is impossible to solve the landfill leakage problem alone.Therefore,after the analysis of the advantages and disadvantages of several common geophysical methods,this paper integrates the charging method,high-density resistivity method and transient surface wave exploration method to detect and study the dam leakage.A variety of geophysical techniques are integrated,verified and supplemented each other,and good results have been achieved in the detection of leakage channels of landfill dams,which provides certain reference for the selection of geophysical methods for similar leakage problems in landfills.
