摘　　要：本文以山东省淄博市博山区南神头—窑广岩溶断块中的地下水为例 ,根据研究区的构造应力场 ,讨论了区内构成断块的断裂构造对本区地下水运动的影响。运用非均质、各向异性地下水非稳定流的理论和 Ritz有限单元法 ,成功模拟了该区裂隙岩溶水的动态。在此基础上建立地下水动态预测模型 。In the paper,the groundwater in Nanshentou- Yaoguang karstmassif,which lies in the south of Boshan dis- trict,Zibo city is investigated. According to the tectonic stress field,the paper firstly discusses various impacts on groundwater movementfrom main faults constituting the karstmassif. Then the theory of unsteady groundwater flow in inhomogeneous and anisotropic aquifer and Ritz finite element method are applied to simulate the dynamic of fracture- karst water. Finally,a model is set up to predict groundwater dynamically. This provides a basis for the rational ex- ploitation and scientific managementof groundwater resources.
