摘　　要：目前我国高铁桥梁建设技术处于世界领先地位,高铁建设中采用了大量的新型结构。结合鲁南高铁洸府河特大桥1-128 m简支钢管混凝土系杆拱桥工程实际,对系杆钢拱桥在施工过程中采取的技术方案、施工措施、质量控制关键环节等进行了详细论述。工程实践证明该工程所采用技术措施合理可行,效果显著,可以为同类工程积累、传递实践经验,具有一定的借鉴、推广意义。At present,China’s high-speed railway bridge construction technology is in the leading position in the world,and a large number of new structures are used in high-speed railway construction. Based on the engineering practice of 1-128 m simply supported concrete-filled steel tubular tied arch bridge of Guangfuhe super large bridge of Lunan high speed railway,this paper discusses in detail the technical scheme,construction measures and key links of quality control adopted in the construction of tied steel arch bridge. The engineering practice proves that the technical measures adopted in this project are reasonable and feasible with remarkable effect. It can accumulate and transfer practical experience for similar projects,and has certain reference and promotion significance.
