摘要
采用稳定和非稳定流抽水试验,得出小李庄水源地的导水系数、压力传导系数、给水度和水跃值,其值分别为273.89m2/d,7402.43m2/d,0.037,2.80m。运用水均衡法,结合试验得出的参数,计算出该水源地浅层地下水允许开采量,证明其符合永城市发展规划所需求的地下水量。
Adopting steady and unsteady flow pumping test, coefficient of transmissibility, coefficient of pressure transmission, specific yield and height of hydraulic jump are attained in the water source of Xiaolizhuang. These values are 273.89m^2/d, 7402.43m^2/d , 0. 037 , 2. 80m respectively. Then the shallow groundwater allowable yields are obtained in the water source using water balance method with the parameters from testing. The results show that the groundwater allowable yield are accord with the needful groundwater quantity regulated by Yongcheng city.
