利用充电法测定地下水的流速流向在我省水利建设中已被广泛应用,通过几年来工作实践证明,它比其它方法简单,在测区内只要有民用井或钻孔就可以进行工作,也不用什么复杂的设备,只需一部我省自制的简易电位计和20公斤左右的食盐即可施测,同时工效高,一般施测只需12小时,如果流速较大的地区有6—8小时即可,测得的资料一般能满足工程建设的要求,因此,利用充电法测地下水流速流向是值得大力推广的。综合我省几年来的实际工作,提出利用充电法测定地下水的流速流向的几点体会:1.水井(钻孔)的选择:必须选择富有代表
The use of charging method to measure the flow velocity of groundwater has been widely used in water conservancy construction in our province. Through years of work experience, it has proved to be simpler than other methods, and it is not necessary to use civil wells or drill holes in the survey area. What complicated equipment, only a self-made potentiometer in our province and 20 kilograms of salt can be measured, while high work efficiency, the general test only takes 12 hours, if the flow rate of the area has 6-8 hours Therefore, the measured data can generally meet the requirements of the project construction. Therefore, using the charging method to measure the flow velocity of the groundwater is worth promoting. Based on the practical work of our province over the past few years, we have proposed some experiences in using the charging method to determine the flow velocity of groundwater: 1. Selection of wells (boreholes): must be represented by wealth
