摘要
贵州黔南地区地下水以岩溶水为主,在需水范围内,基岩很少出露,地表覆盖层往往较厚,运用物探方法能够快速准确的确定最佳钻孔位置。笔者通过在黔南地区多地开展物探找水定井工作,在钻孔验证成功的基础上,总结了在该区寻找岩溶水的最佳物探方法是电阻率联合剖面法和五极纵轴直流电测深法,并分析了比值法在数据处理中的优点。
The groundwater in south Guizhou mainly is karst water,the bedrock hardly imposed in the water-deficient area,the overburden layer of surface is thick,The application of geophysical method can ensure the best position drilling.By geophysical water researching and well positioning in south Guizhou,on the basis of successful drill testification,resistivity combined profile method and five poles direct current electric sounding,which are the best geophysical method in this area are summarized,the advantages of ratio method in data processing is studied.
