基于达索3DE平台的组合梁拱桥BIM设计应用

Application of BIM in Design of Composite Girder Arch Bridge Based on Dassault 3DE Platform

随着桥梁技术的不断发展,拱桥的形式日新月异,使得设计工作难度大大增加.现以深汕大桥工程为案例,在深化设计阶段基于参数化、模板化设计思路应用达索3DE平台(2015X)建立包括主拱、主梁、吊杆、墩台基础、桥面附属工程等结构的一整套组合梁拱桥梁构件库,并完成了全线桥梁的BIM建模、基于BIM模型辅助设计校核、与结构计算分析的对接、对模型构件进行统一编码,提取构件信息,结合GIS的数字沙盘,并形成一套完整的数字化交付成果,为向施工阶段和运维阶段传递数据提供了基础.

With the continuous development of bridge technology,the form of arch bridge changes daily,which greatly increases the difficulty of the design.Taking the Shenshan Bridge Project as an example,based on the idea of parametric and template design in the deepening design stage,Dassault 3DE platform(2015x)is used to establish a complete set of composite girder arch bridge component library including the main arch,girder,suspender,pier and abutment foundation and deck accessories,and the BIM modeling of the whole line of bridges is completed.Based on BIM model,the design verification is aided.Docking with structural calculation and analysis,the model components are unified and coded,and the component information is extracted.Combined with the digital sand table of GIS,a complete set of digital deliverables is formed,which provides a basis for transferring data in the construction,operation and maintenance stages.
