The article studies the detection of the leakage passage of leachate in a waste landfill dam. The leachate of waste landfill has its own features, like high conductivity, high chroma and an increasing temperature, also, the horizontal flow velocity of groundwater on the leakage site increases. This article proposes a comprehensive tracing method to identify the leakage site of an impermeable membrane by using these features. This method has been applied to determine two leakage sites of the Yahu municipal solid waste landfill site in Pingshan District, Shenzhen, China, which shows that there are two leachate leakage passages in the waste landfill dam A between NZK-2 and NZK-3, and between NZK-6 and NZK-7.
本文研究了垃圾填埋场大坝渗滤液渗漏通道的检测。垃圾填埋场的渗滤液具有自身特点，如高电导率、高色度以及温度不断升高，而且渗漏部位的地下水水平流速也会增加。本文提出了一种综合追踪方法，利用这些特征来确定防渗膜的渗漏部位。该方法已应用于确定中国深圳坪山区雅湖城市垃圾填埋场的两个渗漏部位，结果表明，在垃圾填埋场大坝A的NZK - 2与NZK - 3之间以及NZK - 6与NZK - 7之间存在两条渗滤液渗漏通道。
