摘要
以扬州市润扬路快速改造工程为例,通过建筑信息模型(building information modeling,BIM)技术与无人机倾斜摄影技术构建三维实景模型,结合Navisworks平台对施工过程可视化仿真,探讨了BIM技术在城市密集区桥梁施工中的应用。结果表明:施工可视化仿真可以协助施工人员更加直观、全面地了解施工过程,优化施工方案,保证施工进度;对各种材料的计划、调度、使用情况做精细化管理,减少损失和浪费;科学合理地安排吊装设备、钢箱梁运输路线、施工工序,解决交叉道口多、施工空间跨度大、城市环境复杂等城市密集区桥梁施工中钢箱梁安装难题。
Taking the rapid reconstruction project of Runyang Road in Yangzhou City as an example,the application of building information modeling(BIM)on bridge construction in densely urbanized region was discussed by constructing 3D real scene model through BIM technology and unmanned aerial vehicle(UAV)tilt photography technology as well as combining the visual simulation of construction process with Navisworks platform.The results show that the construction visualization simulation can assist the construction personnel to have a more intuitive and comprehensive understanding of the construction process,optimize the construction scheme and ensure the construction schedule.It could also manage the planning,scheduling and usage of various materials in a fine manner to reduce loss and waste.Scientific and reasonable arrangement of hoisting equipment,steel box girder transportation routes and construction procedures has solved the installation problems of steel box girder during bridge construction in densely urbanized region,such as many crossings,large construction space span and complex urban environment.
