摘　　要：大瑞铁路怒江四线特大桥主桥为490m跨上承式提篮拱,拱圈采用4片钢桁架结构。主桥采用移动缆索吊机施工,高空作业多、体量大、对接精度高。项目利用BIM技术对主桥进行全方位、全过程虚拟建造,模拟并优化全部构件吊装顺序、组合、姿态、路径,综合应用多项新技术指导施工,实现建造过程安全、高质量、智慧化,最后总结基于BIM的钢桁架桥组合式数字化拼装技术。The main bridge of the Nujiang-River four-line bridge of Dali-Ruili Railway is a deck handle basket arch bridge.The arch rib adopts four pieces steel truss structure.The moving cable crane is used in main bridge construction,with many high-altitude operations,large scale and high precision.BIM technology is used to build the main bridge virtually in all directions and in the whole process,the hoisting sequence,combination,posture and path of all components is simulated and optimized,to achieve safety,high quality and wisdom,this paper summarizes the steel truss bridge combined digital assembly technology based on BIM.
