摘要 以湖南黄花国际机场找水工作为例,介绍了在长平红层盆地中,如何利用物探方法勘探地下水。使用联合剖面法推断了北东向及东西向断裂构
造,并且北东向断裂构造错断了东西向断裂构造;通过ρs变化率分析,推断出断裂构造的复合部位岩石破碎强烈,是地下水富集的理想地段;通过
激发极化测深,推断了岩溶发育段的深度,并评价了富水性。在物探确定的异常点上,经钻探验证,涌水量达到2 000 m3/d以上。
Abstract :With the combined profile method, the author inferred the existence of NEtrending and WEtrending fault structures in
the logistics base of the Huanghua International Airport, with the former fault structure displacing the latter one. An analysis of
ρs variability suggests that there exists strong shattering at the compounding place of the fault structures, which is thus the
ideal position for underground water accumulation. IP sounding revealed the depth of the karst segment and the water accumulation
degree. Drilling test at the anomaly point determined by geophysical exploration shows that the outflow of water has reached over 2
000 m3/d.
