摘要
岩溶含水岩组及断层破碎带的电阻率与其完整的围岩有明显的电性差异。在多测道电压 ( V/I)剖面图上显示为双峰异常 ,在视电阻率 ( ρτ)断面图上显示为低阻异常 ,为在直流电法无法开展的地区进行找水 ,圈定富水地段。
There is clear electric difference between the resistivity of rock dissolvent contait water groups and fault breaking belt with its complete surround rock,the showing is measure V/I sectional drawing is abnormality of peak-peak value,the showing in ρτ sectional drawing is abnormality of low-resistivity,to provide basis for finding water in area unable used DC method,enclosing full of water area,determining well position.
