Simulation of Bridge Construction Based on BIM+GIS
Bridge construction projects crossing railways,busy roads and complex terrain have high safety risks and are difficult to organize and manage.It is necessary to determine a reasonable construction scheme and optimize the design through simulation in advance.Based on the 3D GIS platform and with the BIM model of bridge engineering as the core,this paper studies the technical route of construction simulation for complex and dangerous working positions of bridge construction,the modeling method of simulation models including BIM model and GIS scene and the building and management technology of bridge simulation 3D scene,then proposes a bridge construction simulation method based on BIM+GIS and develops relevant tool software.The R&D results have been applied to the scheme comparison of construction platform layout for 19# pier of Wenhe Super Major Bridge of Yangquanbei-Dazhai Railway,effectively solving the problems in placement space optimization and platform layout under narrow space and complex environment.
