中文摘要：
地质体3维模型是地学工作者研究的重点和热点，在地质工程、地质灾害预警与防治、矿山管理等方面得到了广泛的应用。地质体3维模型研究涉及构模方法、数据模型、数据结构等多方面的内容。本文在对国内外地质体3维模型领域的研究成果进行对比研究的基础上，综合阐述了地质体3维模型相关研究领域的研究进展，对相关的构模方法、数据结构、实际应用进行了分类对比分析，提出了地质体3维模型应遵循的原则。对地质体3维模型的研究现状进行了综合分析，并就构模方法、数据结构、空间分析等方面进行了深入的阐述。在综合研究前人成果的基础上。提出了多层TIN和TEN的3维地质体模型，并对该方法的可用性做了实验。
英文摘要：
3D Geological Model is the key and focus to learning, geological engineering, early warning and prevention of geological disasters, mine management, and other aspects that have been widely applied. 3D Geological Model involves modeling methods, data model, data structure and other aspects. Based on the comparative study on the research results of three-dimensional geological model in the domestic, it expounds the research progress in the three-dimensional model of geological field. The related modeling methods, data structure and practical application are comparative analyzed and classified, accovding to the three-dimensional geological model of the principles. The comprehensive analysis of threedimensional geological model progress is given in the article, and modeling methods, data structure, spatial analysis has done an in-depth analysis expounded. Based on a comprehensive study on the previous results, a multi-TIN and TEN mixed 3D geological model was proposed and an experiment was carried out to prove the availability of this method.
