渗透系数K是地下水运动研究中的重要水文地质参数之一。准确地获得K值对于研究多层含水层中地下水的运动具有重要意义。文中用模糊数学的综合评判方法定量评价了多层含水层的渗透性,并与传统的加权平均方法做了对比,以此,期望为提供可靠的水文地质系数开劈一个新途径。 The permeability coefficient K is one of the important hydrogeological parameters in groundwater movement research. Accurately obtaining K values ​​is of great significance for the study of groundwater movement in multi-layer aquifers. In this paper, the comprehensive evaluation method of fuzzy mathematics was used to quantitatively evaluate the permeability of multi-layer aquifers, and compared with the traditional weighted average method. In order to provide a reliable new hydrogeological coefficient, a new approach is expected.
