摘要
近年来,由于矮塔斜拉桥兼有梁桥和斜拉桥的优点,具有纤细柔美的美学效果,同时考虑经济性和施工性,在公路和铁路工程中越来越多地被采用。商合杭铁路颍上特大桥为(94.2+220+94.2)m预应力混凝土矮塔斜拉桥,原设计采用先塔后梁的施工方式,为节约工期成本,加快施工进度,进行施工优化,采取塔梁同步施工工艺。
In recent years,low pylon cable-stayed bridges have both the advantages of girder Bridges and cable-stayed Bridges,which have fine and soft aesthetic effects.The yingshang bridge of shanghehang railway is a(94.2+220+94.2)m prestressed concrete low-tower cable-stayed bridge.The original design adopts the construction method of tower first and then beam.In order to save the construction cost,accelerate the construction progress,optimize the construction and adopt the synchronous construction technology of tower-girder.
