摘要
不确定性分析是地下水模型的重点和难点。在介绍UQ-PyL软件不确定性分析功能的基础上,本文通过控制文件将UQ-PyL和地下水模拟软件包PGMS连接,以佳木斯市傍河水源地的地下水模型为例,展示了统计分析、敏感性分析、替代模型、参数优化的功能。结果表明UQ-PyL可很好地应用于地下水数值模拟的不确定分析。UQ-PyL具有用户图形界面友好、功能齐全和操作简单的特点,可广泛应用于具有源代码的地下水模拟程序。
Uncertainty analysis is the emphasis and difficulty in groundwater modeling. Based on the introduction of UQ-PyL software and its functions of uncertainty analysis, a case study on the modeling of riverside groundwater resource in Jiamusi city is carried out to present the functions of statistical design, sensitivity analysis, surrogate modeling and parameter optimization considering both UQ-PyL as control file and PGMS, which is a software package of groundwater modeling. The results show that the UQ-PyL can be applied well to analysis the uncertainty in groundwater models. UQ-PyL is friendly to use with graphical interface, complete functions and simple operation, which can be widely used in groundwater simulation program with source code.
