地下水数值模拟是地下水在多孔介质中分布过程机理的模拟,以流域水量均衡为基础,应用ArcView GIS与FEFLOW专业地下水模拟软件,根据研究区水文地质勘探资料、抽水试验及地下水水位长期观测资料,建立了内陆河流域二维地下水运动模拟模型。采用Kringing、Aki-ma插值方法和Galerkin有限元三角形网格剖分技术,求解模型,模拟了台兰河流域地下水运动特征。从模拟结果可以看出,所建立的水文地质概念模型和数学模型是正确的,选取的水文地质参数和计算的源汇项基本合理,模拟结果与实测数值比较吻合,符合台兰河流域地下水的实际情况,能够进行该区域地下水的动态预报,可为研究区水资源的合理开发提供科学依据和技术指导。
Numerical simulation of groundwater is a simulation of the distribution process of groundwater in porous media. Based on the basin water balance, ArcView GIS and FEFLOW professional groundwater simulation software are used to establish groundwater table based on the data of hydrogeological exploration, pumping test and long-term groundwater table Two-dimensional groundwater movement simulation model in inland river basin. Kringing, Aki-ma interpolation method and Galerkin finite element triangular meshing technique are used to solve the model and to simulate the groundwater movement in the Tailan River Basin. It can be seen from the simulation results that the established hydrogeological conceptual model and mathematical model are correct, the selected hydrogeological parameters and the calculated source and sink items are basically reasonable, and the simulation results are in good agreement with the measured values, in line with the groundwater in the Tailan River Basin The actual situation, can carry on the dynamic forecast of the groundwater in this area, can provide the scientific basis and the technical guidance for the reasonable development of water resources in the study area.
