| 摘 要： | 在探讨水文地质参数空间变异性的基础上,考虑导水系数为常量及参数随空间变量发生改变的情况下,比较交替方向隐式差分法计算地下水二维非恒定流方程的异同。引入算例分别进行计算与分析,得出水文地质参数的空间变异性对地下水非恒定流计算存在影响的结论,进一步说明水文地质参数空间变异性研究工作的重要性与必要性,并提出今后研究工作的建议方向与重点。

| Abstract: | On the basis of considering the spatial variability of hydro-geologic parameters and taking the coefficient of hydraulic conductivity as constant or changing with space variables,the calculations of groundwater two-dimensional unsteady equation by alternating direction implicit difference method are conducted and the results are compared.The case study shows that the spatial variability of hydro-geologic parameters has a certain affect on the calculation of groundwater unsteady flow,and the research on the ... |
