无人机倾斜摄影技术结合BIM+GIS在城市隧道建设中的应用

Application of UAV-Oblique Photography Technology Assisting with BIM+GIS Technology in Urban Tunnel Construction

城市隧道工程建设跨区域广、线路所在地貌复杂、施工难度大、监管问题多。文章利用无人机倾斜摄影生成三维实景模型,结合GIS地理信息系统和BIM建筑信息化,对城市隧道工程的规划选线、隧道开挖施工方式、上部影像测量及巡检等方面进行了应用探索。以广州如意坊隧道工程项目为实践载体,应用表明三维数字化信息管理方式具有数据采集效率高、结果显示直观、分析沟通效率高等优点,在城市隧道建设的辅助方案决策、管理水平提升等方面效果显著。

The construction of urban tunnel project spans a wide area,the landform of the line is complex,the construction is difficult,and there are many supervision problems.This paper uses UAV oblique photography to generate the 3D real scene model,and combines GIS geographic information system and BIM building information technology to explore the application of urban tunnel engineering planning and selection,tunnel excavation construction method,upper image measurement and inspection.Taking The Guangzhou Ruifang tunnel project as the practical carrier,the application shows that the three-dimensional digital information management method has the advantages of high data collection efficiency,intuitive display of results,high efficiency of analysis and communication,and has remarkable effects in the auxiliary scheme decision-making and management level improvement of urban tunnel construction.
