| 摘 要： | 地下水系统数值模型都要求模拟域为有界且边界条件是已知的。本文引入计算边界将无界含水层划分为有界的研究域和半无界的非研究域两个子空间 ,通过求解非研究域定解问题确定计算边界的边界条件 ,使无界含水层转化为有界的研究 (模拟 )域。这个方法应用到轴对称井流和二维平面流数值模型中无界边界条件的转化。

| Abstract: | Simulation field in numerical model of groundwater system is required to be finite and the boundary conditions should be already known.Two sub\|spaces of finite research field and semi\|infinite non\|research field are classified for infinite aquifer herein for boundary calculation.Determine the boundary condition for calculating boundary through solving defining problems of non\|research field and converse the infinite aquifer into finite research field.This method can be used in the conversion of infinite boundary conditions of numerical model with well flow of symmetrical axis and two dimensional plane flow. |
