摘要
通过对三维地质建模各环节的特征分析,在原始数据、插值方法、建模方法、地质复杂性与随机性、计算机和建模人员等六方面概括出了影响三维地质建模精度的主要因素,然后对当前三维构造模型和三维属性模型的质量控制方法进行讨论,并对当前面临的问题预测了区域性三维地质模型质量控制的发展趋势。
The accuracy of 3 D geological modeling(A3 DGM)on geological application, such as spatial analysis, resources calculation and numerical simulation, is important in the progress of geological survey. There is practical significance to analyze the influencing factors of accuracy in the process of 3 D geological modeling and quality control of 3 D model. Through the analysis of characteristics of every step in the workflow of 3 D geological modeling, six factors influence the quality of 3 D geological modeling in the following six aspects: data sources, interpolation method, modeling method, complex and randomness of geological bodies, computer science and modeling experts. The study discussed the quality control method of 3 D structural model(SM)and 3 D property model, and finally forecasted the direction of regional modeling technique development in the future based on the accuracy control of 3 D geological modeling. This paper provides an important enlightenment for modeling in the process of quality control.
