摘要: 有研究结果表明[1],自流井水位发生阶变时,流量与之有同步变化,在此基础上建立了数学模型:ΔV=ΔhSo+ΔQτo即含水层流入井孔水量的增量等于水位阶变量所占的体积与流量变化量在一定的时间内排出水管的水体积之和。并根据自流井水位与流量的关系式Q=C(2gh)(1)/(2)和万全井水位、流量资料,经过公式推导与计算,证明万全井水位阶变异常幅度与水位观测值大小成正比例关系。Abstract: The research resuits show that when water Level in artesian wells shows step-variations, the discharge shows synchronous wariationa.Based on this, a mathematic model has deen estalished:ΔV=Δh.Su + ΔQ.τ, that is, the encreased quantity of water quantity flowed to the well from aquifer is equal to the sum of the volume accupied by water level step-variation quantity and the water volume discharged from water pipe by variational quantity of discharge within a certain time。According to the relationship between water level and discharge in artesian wells, that is, Q=C(2gh)1/2, and water level and discharge data in wanquan well,and by formula computation, it has been proved that the anomalous amplitude of water level step-variations in Wanquan well is directly proportional to the water level observation value.
