摘要
卫运河桥主跨斜拉式预应力混凝土连续扶架梁，是我国铁路桥梁首次采用的新结构。对桁架梁结构及预应力体系、桁架梁杆件预制、拼装、合龙段施工等关键技术作了介绍，并对同类型桥梁设计及施工提出了改进意见。
The stayed prestressed concrete continuous truss beam of The Canal Wei is a new structure that is first used in railway bridge of our country. The key techniques such as the construction of truss beam, the system of prestressing force,the prefabrication and the assembly of the pole of truss beam and the construction of jointed section are presented,and some improved proposals on the design and construction of the same type bridge in the future are also made.
