摘　　要：以预制简支转连续预应力混凝土T梁桥为依托,研究了该类桥梁采用单、双排支座两种方案时上部和下部结构受力、施工工艺和桥梁造价的差异,得出了双排支座T梁在上部结构受力和施工工艺方面更具优势,而在下部结构受力和造价方面劣势明显的结论,为类似桥梁方案选型提供参考。Relying on the prefabricated simple support into continuous prestressed concrete T-beam bridge,the differences in superstructure,substructure,construction technology and bridge cost when this type of bridge adopts single and double row support schemes are comprehensively studied,and the conclusion that the double row supports T-beam has more advantages in superstructure stress and construction technology,but obvious disadvantages in substructure force and bridge cost,which provides a reference for the selection of similar bridge schemes.
