| 摘 要： | 花岗岩地区一般地下水匮乏，找水难度相对较大，采用单一的物探方法效果常常不理想.近年来，通过多幅1：5万水文地质调查工作，采用综合电法在花岗岩地区确定了多处井位，均取得了满意的效果.本文选取2处定井实例，分析了高密度电法剖面和激电测深曲线在花岗岩地区相对富水区域的电性特征.实践证明，高密度电法和激发极化法相结合，可以提高定井的效率和准确性，在同类地层找水工作中具有一定的借鉴意义.

| Abstract: | As granite regions are generally short of groundwater, it is relatively difficult to find water, and the results of using a single geophysical method are often unsatisfactory. In recent years, through a series of 1:50000 hydrogeological surveys, the integrated electrical method is used to determine several well locations in granite regions, which all have obtained satisfactory results. Two examples of locating wells are selected to analyze the electrical characteristics of the high-density electrical profile and IP sounding curve in the relatively water-rich granite regions. The practices prove that the combination of high-density electrical method and IP method can improve the efficiency and accuracy for locating wells, and can also be used as reference for water prospecting in similar strata. |
