摘要
证明了一维承压越流含水层系统不稳定流问题差分格式的稳定性条件．显式差分格式的稳定性条件是Δｔ｛４Ｔ／［μ（Δｘ）２］＋ｂ／μ｝≤２，隐式格式是无条件稳定的．以河间地块一维承压越流含水层为例，根据给出的稳定性条件进行了数值计算，结果表明，在满足稳定性条件时，其计算结果符合实际．
In this paper, the stability constraints of explicit finite difference method for solving one dimensional unsteady leaky confined aquifer is proved to be Δ t{4T/[μ (Δ x) 2]+b/μ}≤2 , and that of implicit finite difference method is Δ t>0 . The numerical results of one dimensional unsteady leaky confined aquifer between two rivers are shown to be consistent with the actual results when the constraints are satisfied.
