序言井群是给水、排水和减压的典型措施。对井群的设计、安装、运行和评价时,要求工程师利用含水层性质的一些知识,对井距和抽水量的各种合理组合在选定点确定其时间——降深关系。如果抽水时间相当短,以及井距很大,则单井降深不受侧旁井点的影响;然而,这在实际上是少有的,而井的干扰则是普遍遇到的。虽然稳态条件不能正规地应用于普通井(除非补给沅是无限的),但现有计算降深的方 Preface The well group is a typical measure of water supply, drainage and decompression. When designing, installing, operating, and evaluating a well group, the engineer is required to use knowledge of the nature of the aquifer to determine the time-depth relationship at various points for a reasonable combination of well spacing and pumping capacity. If the pumping time is relatively short and the well spacing is large, the single well depth is not affected by the side wells; however, this is actually rare, and well interference is commonly encountered. Although the steady-state conditions cannot be applied to normal wells (unless the recharge is infinite), the existing method for calculating depth is
