关中盆地水文地质结构三维建模与可视化
首发时间:2016-01-26
摘要:结合水文地质空间结构的特点,在建立水文地质数据库基础上,提出了多层DEM-三棱柱的面体混合空间建模方法,实现对水文地质空间结构的三维建模,该方法发挥多层DEM模型便于实现层状结构体建模与模型更新,以及体模型擅长复杂地质结构体构模和描述三维空间拓扑关系清晰的特长,并运用于关中盆地水文地质三维空间构建与可视化。结果较好表达了关中盆地的第四系地层、含水层的三维空间真实形态。任意空间剖切生成的剖面图比较正确揭示了关中盆地水文地质空间结构在空间的分布规律。

3D Modeling and Visualization of Geohydrology StructureIn GuanZhong Basin
Abstract:Proposed DEMs-Triangular prism model method based on geohydrology database and spatial structure, achieve 3D hydrogeological model. the method not only play the advantages of DEM for layer structure body and body model for complex geological structure, but easy to update and body topological clear. Finally applied GuanZhong Basin 3D modeling and Visualization ,the result better express the Quaternary and Aquifer spatial distribution, arbitrary profile reveal hydrogeological structure of GuanZhong basin correctly.
Keywords: Geohydrology DEMs-Triangular prism 3D Model GuanZhong Basin Profile
