摘要
在风-海积平原砂地尝试采用高密度电阻率法探测群孔连续抽水形成的降落漏斗,并和实测水位线相互验证。结果表明采用高密度电阻率法可以探测疏干区的二维形态(深度、宽度),高阻区界线与停止抽水时水位线基本是吻合的,说明了高阻区与疏干区的一致性。同时,根据高阻区的形态可以初步判断地下水位总体上是北高南低,西高东低。因此,通过前期采用高密度电阻率法探测降落漏斗形态,后期利用水位观测进行验证的方法,可快速圈定滨海地下水开采地区或水源地的降落漏斗范围。
This study attempt to use the high-density resistivity method to detect groundwater depression. Meanwhile, the results will have a mutual verification with measured water line. The results showed that the high-density resistivity method could detect two-dimensional shape(including depth and width) in dewatering zone Through comparing, the high-resistance region and the water line basically tallies at the end of water pumping. The practice also prove that the water level is higher in north lower in south, and also higher in west lower in east. Therefore, groundwater depression range in coastal plain or water source areas could be delineated through using the high-density resistivity method at prophase and measuring water level at anaphase.
