以深层地下含水层作为巨大的天然储能库,实行“冬灌夏用”和“夏灌冬用”具有重大的节能效果。为此必须研究和求解地下水动力场和温度场。本文以非均质岩溶承压含水层二维不稳定渗流为例利用数模混合仿真来求解地下水动力场。 本文给出了水文地质模型及其求解的模拟结构图、地质和边界条件的模拟方法、数模混合求解中初值的迭代求解及信号的采样、存储和恢复。文中还给出了某一方案的仿真结果。 可以看出利用数模混合仿真研究和求解水文地质问题是可行的,它可以成为水文地质计算和研究的有力工具。
Deep underground aquifers as a huge natural energy storage, the implementation of “winter irrigation summer” and “summer irrigation” has a significant energy saving effect. Therefore, we must study and solve groundwater hydrodynamic field and temperature field. In this paper, two-dimensional unsteady seepage flow in heterogeneous karst aquifer is taken as an example to solve the groundwater dynamic field by using digital-analog hybrid simulation. In this paper, we present the hydrogeological model and the simulation structural diagram of the solution, the simulation method of the geology and the boundary conditions, the iterative solution of the initial value in the hybrid solution and the sampling, storage and recovery of the signal. The article also gives a simulation results of a program. It can be seen that it is feasible to study and solve hydrogeological problems by using mixed numerical simulation. It can become a powerful tool for hydrogeological calculation and research.
