Combined with actual construction process,this article summarises the super large-span prestressed concrete beams construction technology from high template support system,large-span prestressed concrete beams construction and mass concrete construction. It mainly introduces the key point of high template support system,the construction order of prestressed beam and the stretch-draw technique. This will provide reference for the similar projects.%结合工程实际施工过程,从高大支模支撑体系、大跨度预应力梁施工、斜屋面大体积混凝土施工三个方面,总结了国内关于超大跨度预应力混凝土梁的施工技术,重点介绍了高大支模体系控制要点、预应力梁施工顺序、预应力张拉等工艺,以供其他类似工程参考借鉴。
