本文用分段法求解多阶段地下水管理模型。地下水偏微分方程用有限差分和有限元法进行近似离散,形成结点的地下水流代数方程组,并插入优化模型中作为等式约束条件。采用分段法计算,并与集中瞬时法进行对照。文中分析了两种计算方法的特点以及多阶段地下水开发和管理模型的实际应用。
In this paper, the staged method is used to solve the multi-stage groundwater management model. The groundwater partial differential equation is discretized by finite difference and finite element method, and the groundwater flow algebraic equations are formed and inserted into the optimization model as the equality constraints. Using the staged method, and contrast with the centralized instantaneous method. The paper analyzes the characteristics of the two methods and the practical application of multi-stage groundwater development and management model.
