摘 要:地下水数值模拟是水文地质与工程地质专业及相关专业的一门重要的基础课程。该课程要求本科生掌握基本的地下水数学模型、数值算法原理以及常用专业仿真软件的基本操作,并能够通过专业软件或编写程序代码实现模拟仿真进而解决基本的地下水问题(包括水流问题、溶质运移问题和热量运移等)。该研究结合笔者在桂林理工大学教授地下水数值模拟课程的经验,提出注重核心概念理解、课后难点解析、重专业软件学习等教学改革的建议,为培养基础扎实、具有解决实际工程问题能力和自我学习能力的地下水专业人才提出参考思路。

Abstract: Groundwater numerical simulation is an important basic course for hydrogeology and engineering geology majors and related majors. This course requires undergraduates to master basic mathematical model of groundwater, principle of numerical algorithm and basic operation of common professional simulation software, and to be able to solve basic groundwater problems (including water flow problem, solute transport problem and heat transport problem) through the simulation of professional software or programming code. Based on the author's experience in teaching Groundwater numerical simulation course in Guilin University of Technology, this paper puts forward some suggestions on teaching reform, such as core concept understanding, analysis difficulties after-class, and professional software learning. The purpose of this paper is to put forward some reference ideas for training groundwater professionals with solid foundation, ability to solve practical engineering problems and self-learning ability.

地下水是人類赖以生存的重要资源之一,在许多地区地下水是居民生活、工业农业用水的主要来源,然而最近几十年人类活动对地下水资源造成了诸多影响,如过度开采、重金属污染等[1]。我国是一个人均水资源并不充足的国家,人均水资源占有量不到世界平均水平的1/4,水资源的缺乏会影响我国干旱地区的持续发展。对干旱地区地下水循环规律以及人类活动对地下水迁移过程影响的研究显得尤其重要。因此,预测评估地下水的水质与水量,并基于此制定相关政策和方针对我国人民生活质量有重要影响。地下水数值模拟就是为了解决相应问题而开展的一门课程[2-3]。……
