【摘要】 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,借助Arcview GIS和Aqua3D专业地下水水流模拟软件,根据研究区水文地质勘探资料、抽水试验及地下水水位长观资料,建立了秦王川灌区南部地下水非稳定流的二维模型．采用Galerkin有限元三角形网格剖分技术,求解模型,运用识别后的模型预测了秦王川灌区南部在达到设计水平年条件后,5年内地下水位将平均上升0．98 m,盐渍化范围将进一步扩大．更多还原

【Abstract】 The substance of groundwater numerical simulation is the mechanism simulation of ground water in the porous medium. Based on the hydrological geology, hydrological geological parameter obtained from the wells and the long term observed groundwater level data and by using the ArcGIS and professional groundwater soft--Aqua3D, the two dimension transient groundwater flow modes were built in the south of Qinwangchuang Basin. Through the identified model, we concluded that the groundwater level would rise 0.98 m in 5 years and the pickled range would deteriorate when the conditions in the basin reach the designed conditions.更多还原
