摘要: 使用地下水数值模拟软件MODFLOW计算各向异性含水层地下水渗流问题时，不可避免需要考虑以下问题：MODFLOW是否可以使用渗透系数张量进行计算；何种条件下可以进行计算以及如何进行计算的问题。本文通过分析MODFLOW的数学模型、离散方法和差分公式，探讨了MODFLOW中含水层渗透系数张量使用方法、条件和可行性。经过分析认为：MODFLOW可以直接模拟特定条件下的各向异性含水层渗流问题；使用旋转网格方法可以扩展MODFLOW模拟各向异性含水层渗流的应用范围。
Abstract: The following questions must be considered when using the groundwater numerical simulation software MODFLOW to calculate groundwater seepage in an anisotropic aquifer. Whether the MODFLOW can be calculated using the permeability coefficient tensor and under what conditions the calculation can be performed. In this paper, the mathematical model, discrete method and difference formula of MODFLOW are analyzed, and the method, conditions and feasibility of using the aquifer permeability coefficient tensor in MODFLOW are discussed. It is shown that MODFLOW can directly simulate the anisotropic aquifer seepage problem under specific conditions; using the rotating grid method can expand the application range of MODFLOW to simulate the anisotropic aquifer seepage.
