摘　　要：以某高速公路特大桥的滩地引桥上部结构为96×55 m预应力砼连续箱梁采用移动模架现浇施工为工程对象,介绍MSS55型移动模架的构造和施工工艺,对移动模架现浇最不利工况进行了有限元分析以及现场荷载试验,为类似移动模架的设计和施工提供参考。Taking the prestressed concrete approach bridge with box main beam of 55 m span which in-suit casting by the move support system in Expressway as an example,introduces the component and construction technology of the MSS55. Structural deformation stress behavior and field loading test of the MSS55 under condition such as full load were analyzed,the results can be referenced for the design and operation of the similar move support system.
