中文摘要:
      以湖南某生活垃圾卫生填埋场为例,分析充电法、激电法和高密度电法相结合的方法在寻找渗漏径流通道中的可行性和应用性,近期发现该垃圾场下游50 m处的水井有严重污染迹象,且已对地下水系统造成污染,因此对填埋场及周边进行地球物理探测,旨在查明渗漏径流通道的走向、位置及深度等。针对上述目的,采用充电法圈定异常8处,高密度结合激电测深法圈定异常1处。在圈定的异常处进行钻探,伴有大量污水污泥涌出,且抽水试验点上游的水位发生急剧变化,涌水量100 m3/d时,降深13.4 m,证实了三者结合在查找渗漏径流通道及污染趋势方面,具有良好的勘探应用前景。
英文摘要:
      Taking a sanitary land.ll site of domestic waste in Hunan Province as an example, the feasibility and application of the method of combining charging method, induced polarization method and high-density method in searching for seepage channels were analyzed. Recently, it was found that the well 50 m downstream of the land.ll site had serious pollution signs. Moreover, it has caused pollution to the groundwater system and brought great inconvenience to the surrounding residents. Therefore, geophysical exploration was carried out on the land.ll site and its surrounding area, aiming at .nding out the direction, location and depth of seepage channels. For the above purposes, 8 abnormal places were delineated by charging method. The anomaly was delineated by high density combined with IP sounding. Drilling in the delineated abnormal place is accompanied by a large amount of sewage sludge gushing out, and the water level of the upstream of the pumping test site changes sharply. When the water in.ow is 100 m3/d, the depth drops by 13.4 m, which proves that the combination of the three has a good exploration and application prospect in the aspect of .nding the seepage run o. channel and pollution trend, and it has a better guiding signi.cance to the similar work in the future.
