摘　　要：在总结三维地质建模与地下水数值模拟常用软件基础上,选用GMS软件,在黄土台塬灌溉典型区域甘肃省永靖县黑台,开展三维地质建模,结合研究区内部钻孔、边界高程、地层高程数据等基础资料,建立实体地层模型,利用建模结果,综合台塬水文地质条件,建立水文概念模型与数学模型,使用软件内MODFLOW数值计算方法,在高密度电法反演地下水位信息验证下,获得研究区地下水数值模型.结果表明,模拟所得三维地层模型有很好的可视性,能直观展示研究区地层分布情况;地下水水位值与高密度电法反演地下水位分布在台塬中部地下水位有很好的对应关系.Based on a summary of the commonly used 3D geological modeling and groundwater numerical simulation software,we used groundwater modeling system on the Heitai terrace,a typical loess tableland irrigation area in Yongjing County,Gansu Province to build up a 3D geological model.A solids stratigraphic model was carried out,combining the internal hole,boundary elevation,digital elevation model and other basic information in the study area.The formation modeling data were combined with the hydrologic activities of the research area,and then a hydrologic conceptual model and mathematical model were established.The numerical calculation method of MODFLOW in the software was used to obtain a groundwater numerical model for the study area under the verification of the inversion information by electrical resistance tomography.The results showed that the 3D model had a good visibility and could display the distribution of strata in the study area.And the simulated groundwater elevation in the middle of the area had a good correlation with the inversion result.
