三维地质建模及其在隧洞工程中的应用

3D geological modeling and its application in tunnel engineering

地层面的建立是三维地质建模的核心,合理的插值方法对地层面的构建具有重要的影响。本文应用离散光滑插值方法来构建地层面,并建立了三维地质模型。通过一个工程建模实例,详细地阐述了基于DSI插值的三维地质模型构建的关键问题。利用专家知识系统并基于CAD开发前处理程序对原始地质数据进行处理和分析。

The construction of the horizon is the key problem of 3D geologic modeling.Reasonable interpolation method has significant effect on the construction of the horizon.In this paper the Discrete Smooth Interpolation(DSI) is used to build the horizon,and then 3D geologic model is built by these horizons.Through an engineering example,the key problems involved in the process of building the three-dimensional geological model based on DSI are discussed.By the use of the expert knowledge system,a useful program is...
