摘　　要：与定流率抽水相比,定降深抽水不易产生抽水井被抽干的现象,且可以忽略井管储蓄效应,更加适用于确定低渗透性含水层的水文地质参数。文章阐述了国外开展的不同含水层类型和抽水井类型条件下的定降深抽水理论研究,并对比国内的研究现状,展望了今后国内相关研究的方向。Compared with constant-rate pumping,a pumping well is not prone to be drained out and wellbore storage effect can be ignored during constant-drawdown pumping,thus the later is more applicable to determine the hydrogeological parameters of an aquifer with low permeability.This paper summarized foreign theoretical studies on constant-drawdown pumping for different aquifers and pumping wells and pointed out the direction of relevant domestic research.
