摘要
为实现城市道路施工项目周边环境的快速分析,为场地布置、施工方案优化、施工进度模拟、道路改造方案调整、征地拆迁范围确定等提供准确的决策依据,将无人机航测获取的实景地形模型与BIM技术建立的道路结构物参数模型进行融合,建立和更新城市道路施工环境模型,快速获取地物、地貌、影像等空间信息。该模型真实反映了施工环境的变化,可快速提取场地布置、道路交改所需的平面图,方案优化所需的面积、长度、工程数量等,还可实现施工场景的三维漫游,为施工方案优化提供了丰富的空间信息数据,具有空间信息丰富、模型信息准确、环境信息真实、模型更新速度快和可视性强等优势,是城市道路施工信息化、智能化的体现。
In order to realize the rapid analysis of the surrounding environment of urban road construction projects, and provide accurate decision-making basis for site layout, construction scheme optimization, construction progress simulation, road reconstruction scheme adjustment, and scope determination of land expropriation and demolition, this research combined the real terrain model from UAV aerial survey and parametric model of road structures set by BIM technology, established and updated the urban road construction environment mode so as to quickly acquire spatial information such as ground objects, landforms, images and so on. The model, reflecting the changes of construction environment, can quickly extract the plan of site layout and road reconstruction, and the amount of area, length and engineering needed for the optimization of the scheme. It can also realize the three-dimensional roaming of the construction scene, and provide abundant spatial information data for the optimization of the construction scheme. The model has advantages such as abundant spatial information, accurate model information, real environmental information, fast model updating and strong visibility, which is the embodiment of information and intellectualization of urban road construction.
