摘要:: 随着智能化供水管网系统的发展,二维供水管网系统已经无法满足日常工作的需要,无法真实反映管网之间的空间关系。目前,三维供水管网系统发展较快,出现了众多产品,满足了在三维展示、查询等方面的应用,而在管网分析方面大多以二维分析为主,缺乏高程地形数据,三维分析效果差。文中结合高程地形图、ArcScene 和 ArcGIS Engine 技术平台,设计了基于流向的爆管分析算法、阀门追踪算法、横剖面分析算法和纵剖面分析算法,并实现了基于三维地形和三维供水管网的分析算法。最终,采用了实际的城市供水管网数据,对爆管分析算法、阀门追踪算法、横剖面分析算法和纵剖面分析算法进行了实验分析,在算法的可行性、准确性和三维展示的效果上体现了较好的效果,为三维管网三维分析算法的研究提供了一种新的技术参考。

Abstract:: ith the development of intelligent water supply network system,two-dimensional water supply pipe network system has been unable to meet the needs of daily work,unable to truly reflect the spatial relationship between the pipe network. At present,the 3D water supply pipe network system develops rapidly,and there are many products which satisfy the application of 3D display,query and so on. However,most of the pipe network analysis is based on two-dimensional analysis,lacking of elevation topography data and poor three-dimensional analysis effect. In this paper,based on the ArcScene and ArcGIS Engine technology platform of elevation topographic map, the burst pipe analysis algorithm based on flow direction,valve tracking algorithm,cross section analysis algorithm and longitudinal section analysis algorithm are designed,and the analysis algorithm based on three-dimensional terrain and three-dimensional water supply pipe network is realized. Finally,the actual urban water supply network data are used to analyze the experimental results of the burst pipe analysis algorithm,valve tracking algorithm,cross section analysis algorithm and longitudinal section analysis algorithm,which shows that the algorithm is feasible,accurate and effective in 3D display,which provides a new technical reference for the research of 3D analysis algorithm of 3D pipe network.
