长株潭城市群核心区三维空间地质数据库建设方法研究

Research on the Construction Method of 3D Geological Database in the Core Area of Changsha-Zhuzhou-Xiangtan City Group

本文提出采用数字高程模型、地质图空间数据库、工程地质钻孔数据库等多源数据进行综合约束,由地质专业人员在人机交互环境下进行综合解译和推断,建立三维空间地质数据库的方法,该方法在长株潭城市群核心区的实际运用中取得了较好的效果。

Based on 3D geological modeling method of section, this paper presents a comprehensive constraint method by using multivariate data of DEM, geological map spatial database, engineering geological drilling database etc. and by professionals in human-computer interaction environment for geological interpretation and inference, to establish 3D geological database. The practical application of this method in the core area of Changsha-Zhuzhou-Xiangtan city group achieved good results, preliminary evaluation should be better than 1：5 million scales, it can be used to provide 3D visualization application for the site of major projects and underground space utilization.
