摘　　要：以武汉天兴洲公铁两用长江大桥正桥I标段0～022号墩铁路简支箱梁40m下行式移动模架拼装为例，对移动模架支架法拼装、主梁预拱度控制、主梁轴线控制及荷载预压试验等进行叙述，为今后同类型移动模架拼装提供参考。Taking the assembling of the 40 m long under-deck movable shuttering form used for the simply-supported railway box girders on piers No. 0 ～022 of Contract I of the Main Bridge, Wuhan Tianxingzhou Changjiang River Rail-cum-Road Bridge as an example, this paper presents the assembling of the type of the movable shuttering form by the scaffolding method, control of pre-cambering and axis of the main beam of the form and also the load precompressing tests for the form. The presentations in the paper may provide reference for the assembling of similar movable shuttering forms in the future.
