单井的降深与涌水量计算不准,和单井抽水试验求参数不准是一个问题的两个方面,它们既相互影响又相互倚赖。原因在于对单井抽水时地下水运动规律缺乏比较正确的认识。过去常用的单井涌水量和参数计算公式,如裘布衣公式对于这一自然规律的反映尚有一定的局限性,不能全面地正确地概括水位和水量的数量关系。单井计算不准的重要原因是公式中未包括三维流和紊流的影响。本文在对裘布衣公式从二维流扩充到三维流的探讨基础上提出一种计算方法。以供生产中参考,不妥之处请批评指正。
The calculation of single-well depth and influx is not accurate, and the inaccurate parameters of a single-well pumping test are two aspects of a problem that affect and depend on each other. The reason is that there is a lack of a correct understanding of the law of groundwater movement when pumping single well. In the past, the calculation formula of single-well water inflow and parameters, such as the formula of Furukawa-Furukawa, has some limitations on the reflection of this natural law. Therefore, the quantitative relationship between water level and water level can not be comprehensively and correctly summarized. An important reason that a single well is not calculated is that the effects of three-dimensional flow and turbulence are not included in the formula. In this paper, a calculation method is proposed based on the discussion of the expansion of the Furukawa formula from two-dimensional flow to three-dimensional flow.
