摘要: 在利用地球物理方法探测西南岩溶山区地下水,确定宜井孔位时,正确分析、判断引起物探异常源的性质,选择合理的方法是决定能否获得地下水勘查成功的关键。通过分析在广西隆安县多处西南岩溶山区找水的成功实例,提出了适宜本地区的音频大地电场法、音频大地电磁测深法组合的物探找水模式,并对其勘查效果进行浅析,总结出确定宜井孔位时几点经验。供从事西南岩溶山区找水工作者参考。Abstract: IntheutilizationofgeophysicalmethodstodetectundergroundwaterinkarstmountainareasofSouthwestChinaandthede-terminationofsuitablewellposition,thecorrectanalysisandjudgmentofthepropertiesofanomalysourceandthechoiceofproper methodsconstitutethekeytothesuccessfulexplorationofundergroundwater.Basedonananalysisofthecasesofsuccessfulwaterex-plorationinquiteafewkarstmountainareasinLong'anCountyofGuangxi,theauthorsputforwardthegeophysicalwaterexploration modelbasedonthecombinationofaudiofrequencytelluricelectricfieldmethodandaudiofrequencymagnetotelluricsoundingmethod, andmadeatentativeanalysisofitsexplorationeffect.Someexperienceconcerningthedeterminationofsuitablewellpositionwas summedupasreferenceforwaterexplorationworkersinthisregion.
