裂隙-岩溶介质空间水流数值仿真与流场优化

裂隙-溶隙水流系统的数值仿真具有明显的优点，数值仿真试验可以通过多种数值方法，识别流场特征，刻画流场时空演化规律，本文基于研究区地下水系统概念模型。以非均质各向异性渗流模型仿真裂隙-岩溶水流，用有限元法求数值解，先解逆问题反演求参，再解正问题计算地下水开采资源量，耦合地下水数值仿真模型与线性规划，建立地下水优化管理模型。通过设计地下水降深分布求最优开采量的方法，实现对地下水渗流场的优化调控。

Numerical Emulation of Fissure-Karst Water and Optimization of Seepage Field

Based on the condition of hydrogeology in the Zhuliu area, Shandong Province, numerical emulation models of the fissure-karst water are built for control and optimization of the groundwater seepage field in the study area. The groundwater flow is emulated with the seepage model of heterogeneity anti-isotope, and the partial differential equations are solved with finite difference scheme of irregular triangle net. The inverse problem is solved for parameters calculating; then the positive problem is solved to calculate groundwater resources. By optimal control of groundwater seepage field, the optimal exploitation quantity in the overall research area is obtained.
