摘要
在河北省蔚县某井田,使用高密度电法仪对地下水进行充电法流速及流向探测。首先通过盐化测井确定含水层深度,以此确定供电电极A的井身位置为25.14m,然后以井孔为中心,以45°等方位间隔布置测线,分别测量盐化前后的电位值,最后根据观测到的地下水盐晕变化情况,运用等电位线图和公式计算,得出该地下水的运移情况:该研究区地下水流向约是157°,流速约0.143m/h。
In a minefield of Yuxian,Hebei Province,the high density electric method instrument has used in detection of groundwater flow rate and direction through mise-a-la-mass method.Firstly,through salification logging to determine aquifer depth,on this account settled current probe A at the borehole depth 25.14m,then to take borehole as the center,45o equidirectional interval laid out exploration lines to measure potential values before and after salification,finally based on observed groundwater salt halo changes,applying equipotential lines and formula computed the groundwater migration status： groundwater flow direction is about 157o,flow rate about 0.143m/h in the study area.
