摘　　要：跨越铁路、繁忙道路以及复杂地形的桥梁工程施工安全风险高、组织和管理难度大,有必要提前通过仿真确定合理施工方案并优化设计。以3DGIS平台为基础,以桥梁工程BIM模型为核心,研究桥梁工程复杂危险工点的工程施工仿真技术路线,包括BIM模型、GIS场景在内的仿真模型建模方法,研究桥梁仿真三维场景搭建及模型管理技术,提出基于BIM+GIS的桥梁施工仿真方法,并开发完成相关工具软件。该研发成果应用于阳大铁路温河特大桥19#墩施工平台布置方案比选中,有效解决了场地狭小、环境复杂情况下的摆放空间优化、平台布置问题。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.
