地质特征三维分析及三维地质模拟现状研究

自然地质现象极其复杂，三维实体普遍存在，随着地学研究不断深入，三维地质模拟已引起了地球科学界的高度重视，目前已经研制出了多种三维地质模拟软件，并被广泛应用到地质、矿产、水文、物探、地震、环境等各个领域。从地质体结构、构造、类型、分布等方面，系统地分析了地质体三维特征，总结了国内外三维地质模拟软件在地质构造、地质工程、矿山测量、地球物理等方面的开发现状，指出三维地质模拟在软件开发方面存在的问题及在地质数据采集、处理、解释、利用方面所面临的困难，并从三维空间数据结构、技术方法、应用研究等方面阐述了三维地质模拟新进展，最后论述了开展三维地质模拟的意义。

3D ANALYSYS OF GEOLOGICAL CHARACTERISTICS AND STATUS RESEARCH OF 3D GEOLOGY MODELLING

The geological phenomenon is very complicated in natural. Existence of 3D geology bodys is universal. With continual deepping of geoscience developing, 3D geo modeling has been though highly of in the earth science world. At present, many 3D geoscience modeling software have been developed .They have been applied at many geoscience fields so as geology,mineral, geophysical exploration,earthquke,enviroment and so on.This paper makes a systematical summary on 3d characteristics of composition, structure, shape, distribution of geological body. It gives a summary on developing status of 3D geo modeling software of geological structure, geological engineering,mine survey, geophyscal and so on in internal and external country. The problems of software developing and the difficultys of 3D geo modeling in gathering, editing, explaining and using of geological data are pointed out.Advances of 3D geo modeling are set forth in 3D spatial data structure,technologys and methods,application resesrch and so on.Finally,meanings of 3D geo modeling are discussed.
