| 摘 要： | 我国基岩山区普遍存在人畜饮水困难问题，因此解决干旱地区的严重缺水问题已刻不容缓。通过1∶5 万水文地质图幅调查寻找到研究区断裂蓄水构造，从赋水空间、汇水区和径流通道三方面确定了赵老园村找水靶区。采用EH4 和对称四极激发极化相互验证的地球物理勘探方法，在EH4 剖面的基础上，共做激发极化测深点7 个、对称四极电测深点2 个，通过分析EH4 连续电导率剖面和激电测深曲线，确定探采结合井位，实现了在基岩缺水山区高效经济地找水示范。该联合技术具有减少物探资料解译成果多解性、降低勘探成本和风险等优点，解译结果验证了侵入岩与围岩蚀变带、断层构造破碎带等是基岩山区地下水相对富水区，为今后该类岩浆岩严重缺水山区找水提供合理可行的技术借鉴和参考。

| Abstract: | The deficiency of drinking water is a common problem in mountain areas of China. It is urgent to solve the problem of serious water shortages in arid areas. Based on the 1∶50 000 hydrogeological map, the fractured water storage structures were found in the studied area. The water target area for the Zhaolaoyuan village was determined from three aspects: water supply spaces, watersheds and runoff channels. Based on the EH4 profiles, seven polarized sounding points and two symmetrical quadrupole sounding points were obtained by the EH4 and symmetric quadrupole excitation polarization. By analyzing the EH4 continuous conductance speed profiles and the measured depth curves, locations of the mining wells were determined, which can be used as an example of efficiently finding groundwater in water scarcity mountain areas. This joint technology has advantages of reducing the interpreted solutions of geophysical data and the exploration cost and risks. The interpreted results show that the groundwater storage zones are intrusive rocks and the surrounding rock alteration zones and the fault structured zones. The results may provide technical references for locating groundwater in magmatic rock areas of serious water scarcity. |
