| 摘 要： | 曲潭测区内地形较平坦,多为第四系覆盖,表层土质较均匀,接地条件较好,选择五极纵轴电测深法在区内寻找岩溶地下水,通过视电阻率及激电二次场的测量,对物探异常的解译和深部钻孔验证,成功找到日出水量达千吨以上的岩溶地下水,为今后在灰岩地区寻找岩溶地下水提供借鉴意义。采用物探方法寻找岩溶地下水是一种不可替代的勘查方法,可以减少单纯钻探成井的盲目性,提高找水的成功率。

| Abstract: | Based on the flat terrain, quaternary covering, uniform surface soil and good grounding conditions of Qutan survey area ,a new geophysical measuring method with the use of five-pole vertical electrical sounding has been applied to look for underground karst water. By measuring visual resistivity and induced polarization of the secondary field, as well as interpreting the anomalous features of geophysical prospecting and verifying the boreholes in deep sections, an underground karst water source with the daily capacity of over 1000 tons has been successfully found in the edge of Longyan Basin within the Permian Qixia stratum, which achieved good geological results and provided an useful reference for more underground karst water discoveries in limestone areas in the future.The application of geophysical methods is irreplaceable in the discovery of underground karst water. It can effectively reduce the cecity of only using drills to dig wells and improve the success rate of water discovery. |
