基于国产平台的铁路三维设计地形系统研究
Research on Terrain System for Railway 3D Design Based on Domestic Platform
摘要
Abstract
At present,in the field of 3D railway design,foreign commercial platforms still occupy the dominant position in the market,posing a risk of being technologically constrained.In addition,there is a lack of mature and usable terrain systems to support the 3D design of long linear railways in both domestic and foreign 3D design platforms.In response to the above situation,this study first designed a terrain system framework for railway 3D design based on C/S architecture,capable of supporting storage,visualization,and calculation of multi-project and multi-coordinate system terrain data in both online and offline modes.Then,based on the domestic BIMBase platform,this study introduced relevant GIS standards and concepts,and proposed an event-driven scheduling mechanism for large-scale terrain tile data,enabling large-scale 3D terrain visualization for long linear railway design.Subsequently,according to the 3D design requirements of different railway disciplines,the characteristics of the terrain tile data formats and organizational forms were fully considered,and two terrain calculation methods-elevation extraction and terrain excavation-were proposed.Finally,application verification in actual projects demonstrated that the railway 3D design terrain system based on domestic graphics platform constructed in this study can meet the application requirements for smooth 3D visualization and efficient calculation of large-scale terrain data in the process of railway 3D design,thereby effectively improving the work efficiency of railway 3D design.关键词
