系统地分析了影响满堂支架现浇混凝土箱梁平整度的主要因素，并以某工程满堂支架现浇连续箱梁为对象，运用大型有限元分析软件Ansys模拟桥梁结构每个施工阶段的受力情况，详细探究了满堂支架施工时桥面的平整度，提出各个影响因素相应的平整度控制对策，用以改善和提高箱梁桥面平整度的工艺，延长桥面铺装的使用寿命。
繫統地分析瞭影響滿堂支架現澆混凝土箱樑平整度的主要因素，併以某工程滿堂支架現澆連續箱樑為對象，運用大型有限元分析軟件Ansys模擬橋樑結構每箇施工階段的受力情況，詳細探究瞭滿堂支架施工時橋麵的平整度，提齣各箇影響因素相應的平整度控製對策，用以改善和提高箱樑橋麵平整度的工藝，延長橋麵鋪裝的使用壽命。

This paper analyzed the influence of full space supports for cast-in-situ concrete box beam flatness is main factor, and taking a certain engineering of continuous box beam with full support for object, by using large finite element analysis software Ansys simulation of bridge struc- ture in each stage of the construction stress condition, the smoothness of construction deck with full support are indicated in details. Put forward the impact of various factors corresponding to the smoothness control measures, in order to improve and enhance the box girder bridge deck smoothness technology, extend the use life of bridge deck overlay.
