本文依据传统越流理论导出了第一类越流系统井涌水量组成计算式。通过实例对该式进行了机上验算,并绘制出了相关曲线。该式表明,第一类越流系统井涌水量由含水层弹性释放补给量和补给层越流补给量两部分组成;此两种补给量随抽水时间的延续而变化,前者逐渐减少,后者逐渐增大;含水层的导水系数、释水系数和弱透水层的渗透系数、厚度是影响井涌水量的两大重要因素。
Based on the traditional theory of over-flow, this paper derives the formula of well water inflow of the first type of over-flow system. Through an example of the formula on the computer check, and draw the relevant curve. This formula shows that the first type of over-flow system well water discharge from the aquifer elastic release of recharge and recharge layer over-current recharge of two parts; the two recharge with the continuation of pumping time changes, the former gradually decreased, the latter The water conductivity, the water release coefficient and the permeability coefficient and thickness of the aquitard are two important factors that affect the well water inflow.
