在无限分布的含水层中,可以利用计算钻孔抽水水位降深的公式,来测求最经济合理的干扰井之间的距离。本文对钻孔具有越流或无越流补给、含水层等厚或不等厚的情况进行了研究。认为,取水构筑物的费用可因干扰井附加降深的减少而降低,其他费用可采取井距间单位长度的造价来表示。 In an infinitely distributed aquifer, the formula for calculating the drawdown of borehole pumping levels can be used to determine the distance between the most economically sound disturbance wells. In this paper, we study whether the borehole has more or no flow and the aquifer is of equal thickness or unequal thickness. It is considered that the cost of water intake structures can be reduced due to the decrease of the additional depth of the disturbing wells, and the other costs can be expressed in unit cost per well interval.
