论述岩溶地区的水文地质概念模型及其对应数学模型,探讨了Visual Modflow中水流边界条件软件模块在岩溶地区水文地质边界条件处理中的应用。在仔细分析岩溶区水文地质条件和地质构造的基础上,对岩溶塌陷地区边界概化为排水沟边界条件进行详细的分析和探讨,使岩溶地区进行数值模拟边界条件概化更加的合理化,降低模拟的数值模型与实际模型的误差。
The conceptual model of hydrogeology in karst area and its corresponding mathematical model are discussed. The application of software module of flow boundary condition in Visual Modflow to hydrogeological boundary conditions in karst area is discussed. On the basis of careful analysis of the hydrogeological conditions and geological structure of the karst area, the boundary condition of the karst collapse area is generally described as a detailed analysis and discussion of the boundary condition of the drainage ditch, so that the boundary condition generalization of the numerical simulation in the karst area is further rationalized and the simulation is reduced The error between the numerical model and the actual model.
