城市三维地质建模方法研究

Research on urban 3D geological modeling method

新一轮城市地质调查正在开展,城市三维地质模型是城市地质调查工作最直观的表达成果。如何根据城市具体地质情况和已有的城市地质调查成果数据,选择合适的三维模型构建方法,实现二维地质资料向三维应用转变是城市三维地质建模需要研究的问题。文中详细论述了国内外三维地质建模技术研究现状、城市三维地质建模的地质条件和建模数据源以及各种城市三维地质建模方法,能够为城市三维地质建模提供参考。

A new round of the urban geological survey was underway,the urban 3D geological model was the most intuitive expression of the urban geological survey.How to choose the suitable 3D model construction method according to the specific geological conditions of the city and the geological survey results data of the existing urban to realize the transformation from 2D geological data to 3D applications was a problem that needs to be studied in urban 3D geological modeling.In this paper,the current research status of 3D geological modeling technology at home and abroad,the geological conditions and modeling data sources of urban 3D geological modeling,and 3D geological modeling methods in various urban were elaborated in detail,which could provide a reference for 3D geological modeling in urban.
