摘　　要：温州飞云江跨海特大桥19×50m连续箱梁采用移动模架现浇施工。为了安全、高效的完成移动模架的拼装,结合空间场地及材料和机械的配置,采用顶推法进行施工最为可行。采用钢管桩作为顶推支架及临时支墩,完成移动模架的分节段拼装工作,拼装所用材料少,时间短,占用场地小,节约成本且文明施工能得到有效保证。The 19 × 50 m continuous box girder of Feiyun River Sea-Crossing Bridge in Wenzhou are cast-in-place constructed with move support system( MSS). It is the most feasible to use the push method to complete the assembly of the MSS for safety and efficiency,Combing the space site,material and mechanical configuration. Using the steel pipe piles as a push support and temporary buttress to complete the segmental assembly of MSS can provide experience and reference for similar projects. Because the method uses less materials、shorter time and smaller field,moreover,it can cost savings and effectively guarantee the construction of civilization.
