摘　　要：Dupuit稳定井流模型和公式自1863年提出,至今已有一百多年了,时间横跨3个世纪。由于其原理的简单及公式的简洁,人们仍在使用。而人们对Dupuit模型以及有关概念的认识,仍然存在很大的差异和误区。通过分析Dupuit稳定流模型及公式,指出Dupuit模型及公式中本身就不含有影响半径的概念。将Thiem提出的影响半径的概念理解为含水层的一个参数,一个不变的常数,并试图寻求一个具有代表性的平均影响半径是没有理论依据的。It has been more than 100 years, spanning three centuries since Dupuit proposed the steady well flowmodel and the Dupit formula. Due to the simple principle and the concise formula, Dupit formula is still in use.However, there have been a lot of disputes and misunderstandings about Dupuit’s model, Dupuit’s formula andrelative concepts. Through analyzing Dupuit model and Dupit formula, this paper points out that the Dupuit modeland the formula itself do not contain the concept of radius of influence. The concept of the influence radius wasunderstood as one of aquifer parameters, trying to seek a representative average influence radius is lack of enoughtheoretical basis.
