基于BIM与实景技术的桥梁建设管理系统研发

Research and development of bridge construction management system based on BIM and real scene technology

针对实景技术在桥梁建设领域应用碎片化、实景技术成果可用性差、管理困难等问题。提出了一套融合BIM与实景技术的桥梁建设管理系统解决方案。首先提出了在桥梁施工现场获取全景图像、倾斜摄影数据以及三维激光扫描点云这三种实景模型的方法,再将三种模型互为补充应用于桥梁施工过程中的工程量计算、场地布控、进度管理、质量检测及工程量计算等方面实现对施工现场的全面实时监控。最后设计并研发了基于BIM与实景技术的桥梁建设管理系统,在系统中实现了基于实景模型的桥梁可视化进度管理以及安全管理,保证了实景技术成果在多单位各部门之间的传递、共享。为实景技术在桥梁建设领域系统化应用奠定了基础,提高了桥梁建设管理的工作效率与管理水平。

Real scene technology has problems in the field of bridges,such as fragmentation of application,poor availability of technical results,and management difficulties.This paper proposes a set of bridge construction management system solutions that integrate BIM and real scene technology.Firstly,how to obtain three real scene models of panoramic images,oblique photographic data and 3D laser scanning point clouds at the bridge construction site is proposed.Then the three models are complementary to each other and applied to the quantity calculation,site monitor,progress management,quality inspection and engineering quantity calculation in the bridge construction process to realize the comprehensive real-time monitoring of the construction site.Finally,a bridge construction management system based on BIM and real scene technology was designed and developed.The bridge visualized progress management and safety management based on real scene model are realized in the system.It ensures the transfer and sharing of real scene technology achievements between multiple units and departments.This article lays the foundation for the systematic application of real-world technology in the field of bridge construction,and improves the efficiency and management level of bridge construction management.
