摘　　要：由于目前填埋场的渗滤液水位勘察技术不能测得含有多层日均覆盖层的填埋场的渗滤液分布,提出一种新的勘察方法,并在现场开展实验,测量多层渗滤液水位.结果表明,钻孔钻至预定深度并结合套筒的有效止水,利用取水装置提取套筒中的渗滤液,绘制水位恢复曲线,该方法可测出各垃圾层的水位;经测试ZK12孔处有4层滞水位,第1层稳定水位埋深4.76 m,第2层稳定水位埋深10.35 m,第3层稳定水位埋深27.62 m,第4层出现承压水;各垃圾层的饱和区厚度不同,主要受该层垃圾渗滤液的导排情况决定.Due to that water distribution of the landfill which contains multiple daily coverage layers cannot be measured through the water level reconnaissance technologies at present, a new reconnaissance method is proposed, and experiments are carried out on site to measure the multi-layer water levels. The results show that water level of each waste layer can be measured by implementing drill- ing to a preset depth in combination with effective water sealing of the sleeve, extracting the water in the sleeve and drawing a water level recovery curve; testing results show that four layers of water levels are located at the hole ZK12, wherein the buried depth of steady water level is 4.76 m on the first layer, the value is 10.35 m for the second layer, the value is 27.62 m for the third layer, and confined water exists on the fourth layer; different saturation thicknesses of each waste layer are mainly decided by drainage of landfill leachate on each layer.
