摘要
该文从二维地质建模的概念出发,探讨了其一般过程,包括地质变量预测、地质特征解译、空间分析等,并介绍了三维地 质建模的体视化方法,最后以润扬长江公路大桥工程为例,运用切片级重建方法,建立地质模型,并进行了三维地质分 析。实践表明,三维地质建模技术是认识复杂地质体的空间关系和特征的强有力的工具,具有广阔的应用前景。
The paper discusses the general process of 3D Geoscience Modeling from its concept including prediction of
geological variables,interpretation of geological characteristics and spatial analysis etc and also introduces the method of Volume Visulization in 3D Geoscience Modeling. Then a project example of Runyang Changiiang River Road Bridge is given to explain this modeling process.The practice shows that 3D Geoscience Modeling technique is a powerfultool to analyse complex geological objects,and it has a wide appliedperspective.
