摘　　要：南京大胜关长江大桥是京沪高速铁路的重点工程,主桥采用三主桁空间桁架结构、Q420qE高性能结构钢、板桁组合结构与整体桥面结构、以及长吊杆抑振等关键技术。介绍南京大胜关长江大桥的建桥条件与技术标准、桥型方案比选与总体布置以及钢桁拱结构方案,重点论述所采用关键技术的研究与运用。Dashengguan Changjiang River Bridge in Nanjing is a key construction project of Beijing-Shanghai High-Speed Railway. A number of the critical techniques, such as the three main truss spatial structure, Q420qE high performance structural steel, plate and truss composite structure, monolithic deck structure and vibration suppression for long hangers, have been applied to the Bridge. The construction conditions, technical standards, bridge type scheme comparison, overall arrangement and steel truss arch structure schemes of the Bridge are presented herewith and the study and application of the adopted critical techniques are described in particular detail.
