Three-Dimensional Structural Modeling Technique

三维构造建模是三维地质建模的核心内容，主要揭示地质构造的几何形态和拓扑关系.三维地质建模在许多地质领域发挥着越来越重要的作用，对三维构造建模技术提出了更高的要求，使其能解决更加复杂的地质问题，能够更精细地刻画地质构造.从三维构造建模的应用需求入手，回顾了领域现状，系统阐述了三维构造建模的基本要素、地质规则及构造模型表达方法，以促进三维构造建模理论向完善化发展.同时分析了传统三维构造建模流程中的难点，指出了需要解决的关键技术，并对当前常用三维构造建模方法的优缺点进行剖析，对其今后的发展趋势和方向进行了预测.
Three dimensional structural modeling is the core content of the 3-D geological modeling, which mainly reveals the geometry and topology of geological structure. The increasing importance of 3-D structural modeling technique in all geological fields induces higher requirements, that is, the modeling should be capable of addressing more complex geological conditions, allowing for more precise characterization of geological structures. This paper starts with the demand of 3-D structural modeling in actual geological application, explains three essential elements systematically, puts forward geological criteria and geospatial data model, and hence improves the modeling theory. Difficulties and key technology associated with 3-D structural modeling are discussed, the future development trend and direction are predicted through analysis of advantages and disadvantages of various modeling methods used by modern 3-D structural modeling
