南京大胜关长江大桥是京沪高速铁路的重点工程，主桥采用三桁空间桁架结构，为2×(84+84) m 连续钢桁梁+(108+192+336+336+192+108)m六跨连续钢桁拱桥。本文主要介绍三桁钢桁梁架设中墩顶布置、钢梁位移调整施工技术，为以后同类型桥梁施工提供借鉴。
The Construction Techniques of pier top arrange and steel bridge displacement adjust for Three Steel Truss Girders of Dashengguan Changjiang River Bridge in Nanjing
Dashengguan Changjiang River Bridge in Nanjing is a key construction project of Beijing-Shanghai High-Speed Railway. The main bridge is the three main truss spatial structure,whichis composedof twounitsof (84+84) m continuous steel truss girders and six spans of (108+192+336+336+192+108) m continuous steel truss arches. The paper main introduce the construction techniques of pier top arrange and steel bridge displacement adjust, and have success-ful experiences for the same bridge construction in the future.
