BIM技术在牟汶河大桥改扩建施工中的应用

BIM technology application in reconstruction and expansion of Muwenhe bridge

在牟汶河大桥改扩建施工中,利用BIM仿真对施工组织计划进行进度推演核查和问题反馈,指导施工单位合理安排工期和设备投入;利用无人机倾斜摄影技术对施工现场进行三维实景构建,将桥梁BIM模型与三维实景相融合;基于Web端BIM+GIS协同管理系统实现桥梁施工信息的集成可视化管控。基于BIM模型实现了施工文档和数据的综合管控,提高了项目施工期的可视化集成管控能力。

In the reconstruction and expansion of Muwenhe bridge,we uses BIM simulation to carry out progress demonstration verification and problem feedback on the construction organization plan restricted,to guide the construction company to reasonably arrange the construction period and equipment investment.Using UAV tilt photography technology to carry out three-dimensional real scene construction on the construction site, the bridgeBIM model is integrated with three-dimensional reality.Based on the Web BIM+GIS collaborative managementsystem, the integrated visual management and controlof bridge construction information is realized. Based onBIM model, the integrated management and control ofconstruction documents and data is realized, which greatlyimproves the visual integrated management and controlability during the construction period of the project.
