一、有限单元法在地下水资源管理中计算水位动态的应用掌握区域地下水位动态变化规律是地下水资源管理中的重要环节。目前,一些常规的做法是在开采区的影响范围内打足够数量的观测孔,进行定期的长期观测,以取得水位动态观测资料,作为分析地下水动态变化的依据。显然,这是一项工程庞大、造价昂贵的工作。当然,这是不得己的事情。但在这种情况下,作为数值解的有限单元法(或差分法)却可用来解得在极其复杂的水文地质条件下的数学模型。求解结果,用电子计算机近似地计算区域地下水位,预测其动态 First, the finite element method in the calculation of groundwater resources in the dynamic management of water level Grasping the regional dynamic changes in groundwater level groundwater resources management is an important part. At present, it is common practice to strike a sufficient number of observation wells within the area of ​​influence of the mining area and conduct regular, long-term observations to obtain dynamic observations of water level as a basis for analyzing the dynamic changes in groundwater. Obviously, this is a huge project, expensive work. Of course, this is an unreasonable thing. However, in this case, the finite element method (or difference method) as a numerical solution can be used to solve mathematical models under extremely complicated hydrogeological conditions. Solve the result, calculate the groundwater level of the area approximately by computer, forecast its dynamic
