德阳市旌阳区某水源地地下水可开采资源评价

Evaluation of Groundwater Recoverable Resources in a Water Source Area in Jingyang District, Deyang City

为重新拟选水源地,使其满足每天4×104m3的开采量,在水文地质钻探的基础上进行潜水非完整井单孔抽水试验,采用潜水非完整井稳定流公式计算出渗透系数K,将拟选水源地布设的18口井假象为一口大井计算地下水可开采资源量。结果表明研究区平均渗透系数K为52.63m/d,地下水可开采资源量为1561.3×104m3/a,达到设计开采要求。

In order to reselect the water source to meet the daily production of 4×104m3,a single-hole pumping test of submerged incomplete wells was performed on the basis of hydrogeological drilling.The permeability coefficient K was calculated by using the steady flow formula of submerged incomplete wells.The illusion of 18 wells in the proposed water source area is considered as a large well to calculate the recoverable groundwater resources.The results show that the average permeability coefficient K of the study area is 52.63m/d,and the amount of groundwater recoverable resources is 1561.3×104m3/a,which meets the design and mining requirements.
