| 随着三维建模技术的日益发展，单一数据源建模已不能满足建模需求。文中通过对多源数据建模方法的阐述，综合地质、物探、化探、遥感、钻探等多源数据的融合方法进行详细解释。将多源数据按表现形式划分为图件类、文字信息类，并通过一系列数据处理工作将原始数据整合至三维空间数据库。以GoCAD建模软件为平台，详细阐述了地形地貌、钻孔、地层、构造、岩体、矿体等对象的建模实现方法，引入GoCAD软件的半自动化流程建模法建立构造-地层实体模型，并提出两种岩体实体建模方法，实现岩体实体模型的构建，最终构建相山火山盆地三维地质实体模型。 |

| With the development of 3D modeling technology, modeling based on single data can not satisfy the present needs of probing the deep subsurface in more detail. This paper presents the methodology of multi-source data modeling. First, various kinds of data are integrated, including geology, geophysics, geochemistry, remote sensing, drilling and others. Second, these multi-source data are divided into two categories: picture information and text information. Third, the original data are integrated into 3D spatial database by data processing. Then, using the software GoCAD as a platform, 3D modeling on topography, geomorphology, drilling, stratigraphy, structure, rock mass and ore body is performed. In this software, the semi-automated process is adopted to build a tectonic-strata model, for which two methods are proposed to establish rock mass solid models. Finally, as an example, this method is applied to 3D modeling of the Xiangshan volcanic basin in Jiangxi Province. |
