【摘要】 以目前城市立交桥中常用的异形变截面多室连续箱梁桥为背景,研究了对其进行施工控制的主要内容和方法,并应用到实际某桥的工程实践中。应变监测与理论分析结果基本保持一致,主桥截面应力正常,整桥的线型符合设计要求。本文的方法可供城市立交桥的施工和设计参考。更多还原

【Abstract】 Taking the shouldered continuous box girder bridge as the subject investigated, this paper studied the primary converge and method of the construction control, which was applied in the engineering practice. The comparison between the monitoring and calculating results showed that they had a good agreement. The cross - section stress was normal and the linearity of the bridge was according to the design requirements. The proposed method could be consulted in the engineering practice and design.更多还原
