以在建佛陈大桥为工程背景，从大节段吊装施工阶段主梁受力、变形情况，成桥状态下主梁关键部位上下缘应力大小、成桥位移，钢箱梁制造线形计算等几方面内容与常规小节段悬拼施工进行对比分析，从设计计算方面论证了钢箱连续梁桥中跨大节段整体吊装施工方案的可行性，分析结论对同类桥型设计具有一定参考意义。
以在建彿陳大橋為工程揹景，從大節段弔裝施工階段主樑受力、變形情況，成橋狀態下主樑關鍵部位上下緣應力大小、成橋位移，鋼箱樑製造線形計算等幾方麵內容與常規小節段懸拼施工進行對比分析，從設計計算方麵論證瞭鋼箱連續樑橋中跨大節段整體弔裝施工方案的可行性，分析結論對同類橋型設計具有一定參攷意義。

Taking in-building Fochen bridge as the engineering background, the article compares major beam stress and deformation conditions at large-section hoisting stage, upper-lower beam stress, completed bridge displacement and steel-box-girder linear calculation to conventional small-section cantilever construction, and discusses the feasibility of large-section hosting construction scheme of steel-box-beam bridge from as-pects of design and computation. Thus, the analysis conclusions will have certain referring meaning for similar bridge design.
