在一定地质条件下,环形自然电场法和充电法是测量地下水流向和流速的快捷、简便的方法。我们应用这两种方法在广东某地工程勘查中确定地下水流向和流速,取得了满意效果,查明了地下水径流分布规律。1 水文地质概述本区属低矮丘陵山区,面积约1.3km~2。地下水主要是孔隙水、构造裂隙水及岩溶水。孔隙水主要富存于工区北部和沟谷 Under certain geological conditions, the natural circular electric field method and the charging method are quick and easy methods to measure the flow and velocity of groundwater. We apply these two methods to determine the groundwater flow and velocity in the engineering exploration in a certain place in Guangdong. The satisfactory results have been obtained and the distribution of groundwater runoff has been ascertained. 1 Overview of hydrogeology This area is low hilly area, an area of ​​about 1.3km ~ 2. Groundwater is mainly pore water, fracturing water and karst water structure. Pore ​​water is mainly found in the northern part of the work area and in the valleys
