【摘要】 在对地质体模型研究分析的基础上,提出了一种基于四面体体元构建地质体模型的方法。该方法把DEM地层看作是由四棱柱集构成,通过将四棱柱分解成四面体,利用四面体体元构建地质体模型,有效地简化了构建地质体模型的难度;实验证明了该方法的有效性。更多还原

【Abstract】 This paper puts forward a method based on the tetrahedron element to construct a geological body model.The method uses quadrangulars to make up the DEM stratum model,decomposes a quadrangular into five tetrahedrons,and makes use of the tetrahedron as the basic volume element.It effectively simplifies the difficulty of constructing the geological body model.The validity of the method has been proved by experiments.更多还原
