| 中文摘要: |
| 为了研究花岗岩贫水区找水难题，本文在总结花岗岩地区地下水赋存类型的基础上，对不同类型的地下水赋存特征进行了分析，并针对花岗岩地区主要赋水类型——构造裂隙水、风化壳裂隙水，选择以电阻率为观测参数的高密度电法和音频大地电磁测深法进行了探测研究。本文通过分析山东临朐县两个花岗岩地区找水的成功实例，表明该两种方法在花岗岩地区找水工作中能取得较好的探测效果。 |

| In order to study the difficult problem of finding water in granite poor water area, based on summarizing the occurrence types of groundwater in granite area, this paper analyzes the occurrence characteristics of di.erent types of groundwater, and explores the main water bearing types of granite area——structural .ssure water and weathered crust .ssure water, and selects resistivity as observation parameter to explore high-density electrical method and audio frequency magnetotelluric sounding method. Through the analysis of two successful examples of water exploration in two granite areas in Linqu County, Shandong Province, it is shown that the two methods can achieve better detection results in the granite area. |
