摘　　要：大跨度连续钢腹板刚构桥悬臂施工中,由于跨度大控制不准确,容易造成线性偏离设计要求,或者合拢困难等工程问题。所以在施工过程中,对桥梁施工的线性进行控制进行十分必要的深入研究,结合XX连续T型钢腹板刚构桥的悬臂施工监控量测方案,采用卡尔曼滤波法来分析连续T型钢腹板刚构桥悬臂施工线性控制中误差的分析,通过数据分析和详细的演算并结合工程实际来验证施工控制误差调整的常用方法和原理,同时也为类型工程施工控制提供有效的借鉴经验。Due to the large span and inaccurate control of Long-span continuous rigid frame bridge in cantilever construction,it is prone to cause the linear deviate from the design requirements,and engineering problems like folding difficulty.So in large span continuous rigid frame bridge construction process,it’s necessary to perform in-depth research of the linear of bridge construction control.Combined with the cantilever construction monitoring and measurement scheme of continuous steel web rigid frame bridge,the Kalman filter method was used to analyze the error analysis in the linear control of continuous steel web rigid frame bridge construction,and the common methods and principles of construction control error adjustment were verified through data analysis and detailed calculation combined with the engineering practice,which also provided effective reference experience for the construction control of type engineering.
