本文首次应用卡尔曼滤波法处理在斜拉桥结构施工中挠度和索力与设计不一致的困难问题。此法特点是逐步通过实际测量数据算出索拉力的调整值,以满足刚性支承连续梁的设计要求,并在最后阶段达到所要求的挠度及内力状态。泖港大桥应用此法进行控制,其最终挠度与设计值仅差2厘米。 For the first time, the Kalman filter method is applied to deal with the difficult problem of inconsistency in deflection, cable force and design in the construction of cable-stayed bridges. The feature of this method is to calculate the adjustment value of the cable tension gradually through the actual measurement data to meet the design requirements of the rigid support continuous beam and achieve the required deflection and internal force state in the final stage. The Dagang Bridge is controlled by this method. The final deflection and design value are only 2 cm apart.
