| 摘 要： | 本文基于华东院自主研发的GeoStation地质三维勘察设计系统,设计一种城市片区地质三维建模技术方法。该方法首先采用地质剖面作为地质拓扑剖面,其次使用地质拓扑剖面将城市片区划分为若干城市区块,再次使用GeoStation系统的地层自动建模功能独立构建城市区块模型,最后将城市区块拼合为整体模型。该方法集成在GeoStation系统中,并在某城市级BIM应用中进行应用,结果表明该技术方法可行,实现了海量庞杂地质建模数据的高效管理,构建的地质三维模型可满足某城市BIM平台数据要求,为城市地理空间信息建模提供新的手段,也为其他城市开展数字化建设和智慧化管理提供范例。

| Abstract: | In this paper, a method of 3D urban area geological modeling based on GeoStation is proposed, which was developed independently by ECIDI. Firstly, the urban area is divided into several urban blocks according to topological division. And the shared geological sections are drawn on the interface of adjacent blocks. Then, the geological 3D models of all urban blocks are constructed by using survey data and geological sections. Finally, 3D urban area geological models are joined by the seamless spicing method. This method is integrated in the GeoStation system and applied to a city-level BIM project. The results show that this technology is feasible, and realizes the efficient management of massive and complex geological modeling data. The resultant three-dimensional geologic model can meet the data requirements of a city BIM platform, providing new means for urban geospatial information modeling, and an example for carrying out digital construction and intelligent management in other cities. |
