摘要
三维地质体建模能以三维真实感图形的形式形象地表达地质构造的真实形态、特征以及三维空间物性参数分布规律,成为地质信息可视化的发展方向。南昌地区已进行的地质勘查工作,利用积累的成果资料,首次建立南昌地区三维地质模型。由于资料来源的多样性和对红层下伏地层勘查程度的不足,建模数据的提取和处理较为复杂。讨论资料收集、数据提取及处理和建模步骤,为类似条件的地质建模提供方法参考。
3 D geo - spatial modeling is the developing direction of visualization of geological information, as it vividly expresses the true form, characteristics, and 3 D physical parameters distribution of the geological structure in the form of 3 D realistic graph. As plenty geological exploration work has been done in Nanchang area, a 3d geological model can be preliminarily built based on the exploration achievements. The data extraction and processing is complicate because the exploration achievements present in many forms and exploration work the below red beds is inadequate. The paper detailly described how to collect exploration achievements, extract and process the data to build the model, and it can be considered as a reference for 3 D geological modeling on complicate situation as the paper discribed.
