城市地下空间工程信息数据库结构的研究与建立

从地下空间工程分类出发,分析了空间数据具有的空间特性、时间特性和专题特性。在分析空间数据管理方式和三维地下空间工程可视化建模需求的基础上,提出了地下空间工程几种简化的数据模型:点模型、线模型、面模型及由简单模型组合的复杂体模型。按地下空间工程数据管理需求进行地下空间工程点表结构、线表结构及面表结构及其属性的研究,利用GeoDatabase数据模型实现了地下空间工程信息数据库结构的建立。最后对数字地下空间工程的发展给出了建议和展望。

Research and Setup of the Information Database Structure for Urban Underground Space Project

This article based on the classification of underground space projects analyzes the space characteristics, time characteristic and special characteristics of spatial data. On the basis of analyzing the spatial data management mode and the needs of three-dimensional visual modeling for underground space project, this paper puts forward several simplified data models of underground space project: point-model, line-model, surface model and complex block model which combines several simple models. On the basis of the management needs, the point-structure, line-structure surface—structure and attribute of underground space project are studied, and by using GeoDatabase-Model the underground space project information database structure is built. It also gives the recommendations and prospects of the digital underground space project.
