摘要
本文根据水源地水文地质条件,结合抽水试验数据资料,确定该区域含水层平均厚度、单井涌水量、渗透系数、影响半径及水力坡度等水文地质参数,采用水均衡法计算地下水资源量,分析补给量与排泄量平衡情况,采用开采系数法确定地下水可开采量,并分析区域地下水位动态变化趋势。
In the paper,according to hydrogeological conditions of water source,pumping test data is combined for determining aquifer average thickness,single-well water inflow,permeability coefficient,influence radius,hydraulic gradient and other hydrogeological parameters in the region. Water balance method is adopted to calculate groundwater resources. Recharge and excretion balance situation is analyzed. Exploitation coefficient method is adopted to determine groundwater exploitable amount. Dynamic change trend of underground water level in the region is analyzed.
