最近几期“水文地质工程地质”月刊介绍了几个有关确定影响半径的新方法,例如第9期中潘天杭同志之“用降落漏斗体积法求潛水含水层中抽水时之影响半径”及第11期中宁有义同志之“测定影响半径的新方法”。首先肯定两位作者的研究精神是值得学习的,但他们没有考虑实用上的方便,也缺乏用实际资料来检验公式的准确性,就潘天杭同志所推导的公式来说,不但在计算上非常复杂,应用起来不方便,而且公式中的 M 值难于精确选定。在本文中仅就宁有义同志(以下简称原作者)提
The latest issue of “Hydrogeology and Engineering Geology” has introduced several new methods for determining the radius of influence. For example, in Chapter 9, Comrade Pan Tianhang, “Impact radius when pumping water in a submerged aquifer by the method of landing funnel volume” and No. 11 Ning justice comrades “Determination of the impact of radius of a new method.” First of all, it is worthwhile to affirm the research spirit of the two authors. However, they did not consider the practical convenience and lacked the practical data to test the accuracy of the formula. Comrade Pan Tianhang’s formula was not only computationally complex , It is inconvenient to use, and the value of M in the formula is difficult to select accurately. In this article, only Ningyouyi comrades (hereinafter referred to as the original author) mention
