摘要
对上跨既有道路的公路及城市立交桥钢混组合结构中复杂线形山字形截面开口钢箱梁在顶推过程中位移、应力进行监测分析,结果表明:采用顶推施工技术并配备精细的施工监测可以确保桥梁结构安全。
The displacement and stress of steel box girder with complex linear gable section in steel-concrete composite structure of highway and urban overpass across existing road during jacking are monitored and analyzed. The results show that the safety of the bridge structure is ensured by adopting the pushing construction technology and equipped with fine construction monitoring.
