多孔观测井抽水试验在应用裘布依公式计算渗透系数时,会出现渗透系数多值,计算量大的弊端.针对多个观测井的抽水试验,提出一种以观测井动水位和补给半径及过滤器半径为参数求得近似系数,推出渗透系数的简单计算方法,有效避免了渗透系数多值的问题,并且减小了计算量,为以后工程应用提供参考.

When using Dupuit formulation for calculating permeability coefficient of wells pumping, some prob-lems, such as too many permeability coefficients, demand much calculating tasks. We put forward a a simple cal-culation method which use exact water level in wells and filter radius to deduce approximate coefficients, aiming at reducing the amount of calculation, and providing reference for later engineering application.
