第一类越流系统井涌水量组成问题探讨

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。

INQUIRIES ABOUT THE COMPOSITION OF THE WELL YIELD OF THE FIRST LEAKAGE SYSTEM

According to the traditional leakage theory, this paper advanced a calculating formula for composition of well yield of the first leakage system. Through the living examples, the formula was checked by computers and the diagrams of relative curves were drawn.The formula shows. (1)The well yield of the first leakage system consists of the two parts the elastic storage of the aquifer and the leakage yield of the leaky layer; (2)These both feeder yields are chageable along with the continuance of pumping. The former is getting smaller and latter larger; ( 3 ) The main factors affecting the well yield are the transmissivity and water yield coefficient of the aquifer as well as the permeability coefficient and thickness of the leaky layer.
