抽水井单位涌水量并不就是含水层导水系数——与兰太权先生商榷

兰太权先生发表3篇文章公布其多年探讨井抽水的单位涌水量和渗透系数或导水系数的关系，认为其提出了一个新的公式和论断“单位涌水量就是导水系数”，并认为传统径向稳定井流理论是错误的，在行业内应改用他提出的新理论、新公式。本文指出其文章中存在的若干问题，说明其公式或理论的不合理和不能用于实际的情形，并阐明抽水井单位涌水量不能等同于含水层导水系数。

The specific well capacity is not the same as the transmissivity of the aquifer tapped by the well-For discussion with Mr. Lan Taiquan

Groundwater; pumping well; steady flow of groundwater; coefficient of permeability; transmissivityMr. Lan Taiquan published 3 papers concerning the relationship between the specific well capacity and the coefficient of permeability or the transmissivity, to which he has devoted himself for many years. He declared that he proposed a new equation and a new argument “The specific well capacity is the transmissivity”. He pointed out that the traditional theory of steady radial flow of groundwater is wrong and that his new theory and equation should be used in the field of hydrogeology. In this article, several problems arising in Mr. Lan’s papers are put forward and discussed. The unreasonable aspects and inapplicability in practical situations of his theory and equation are described, and the argument “The specific well capacity is not the same as the transmissivity of the aquifer tapped by the well” is also clarified.
