| 摘 要： | 针对排水管网管理业务的不同需求，研究排水管网的多尺度几何语义表达方法，本文提出了包含“源—网—厂—汇”的排水管网多尺度几何语义模型。通过对排水管网组成要素及其相互间的关系进行系统地分析，并参考CityGML规范，提出了排水管网多细节层次模型；根据不同排水管网要素的特点，采用符号化及BIM等建模方式分别构建了不同细节层次的排水管网要素模型，支持排水管网多尺度可视化分析。并以某区域的排水管网数据为例，对本文提出的建模方法进行验证。

| Abstract: | A multi-scale geometric and semantic model of drainage network involving "source-network-factory-sink"by studying the multi-scale geometric and semantic expression method of drainage network is proposed in this paper to meet the different requirements of drainage network management. Through the systematic analysis of the components of drainage network and their interrelations,the LODs model of the drainage network is designed by referring to the City GML specification. And then according to the characteristics of the different components of drainage network,the three-dimensional models of the components of drainage networks in different LODs are separately constructed by symbolic modeling and BIM modeling and other methods to realize the multi-scale representation of drainage network. The data of drainage network in a certain area is used to verify the modeling method proposed in this research. |
