摘　　要：为解决桥梁施工过程中,不同桥墩标高误差过大问题,依托某波形钢腹板连续刚构桥工程,利用卡尔曼滤波算法,根据已施工阶段的标高,经过卡尔曼滤波算法的计算,得到待施工部分的立模标高最优值,以确定桥梁各控制点处的施工预拱度和计算精度。由卡尔曼滤波法得到的预测值,和成桥线形下的实测标高和设计标高进行数据分析,确定卡尔曼滤波算法可为桥梁关键施工阶段的立模标高值确定提供参考,更有效地提升波形钢腹板连续刚构桥的线形控制精度。In order to solve the problem of pier elevation error in bridge construction,a certain continuous rigid frame bridge with corrugated steel webs is taken as the research object.According to the elevation of the finished parts of the project,the Kalman filtering method is used to obtain the best value of the elevation of the parts to be constructed,and then determine the construction camber and calculation accuracy of each control point of the bridge.The predicted value obtained by the Kalman filtering method and the measured elevation and design elevation of the bridge are compared,and the results show that the Kalman filtering method can provide reference for the determination of the vertical height value in the key construction stage of the bridge,and can effectively improve the line shape control accuracy of the continuous rigid frame bridge with corrugated steel webs.
