摘　　要：在某些特定环境下大跨径桥梁施工过程中,拱肋吊装施工阶段由于受限于复杂地理位置及工况,导致安装过程产生较多难点。通过研究分析,采取对原设计节段的再划分,解决拱肋节段的陆路运输受限问题、建立三维模型分析及优化解决吊点设置等一系列施工方法,以确保复杂的异形拱肋吊装作业顺利进行。During the construction of long-span bridges in some special environments,arch rib lifting is restricted by complex geographical locations and working conditions,leading to many difficulties in installation.Through study and analysis,a series of construction methods are applied,including the redivision of original design sections,solutions to constraints in land transportation of arch rib sections,and establishment of 3D models for analysis and optimization of the setup of lifting points,to ensure the successful lifting of complex special-shaped arch ribs.
