针对系杆拱桥吊杆张拉的具体问题 ,探讨了利用卡尔曼滤波法进行施工控制的方法。选定拱轴线形为预测和控制的对象 ,利用卡尔曼滤波法消去施工时混杂在信号中的随机噪声 ,得到系统统计意义上无偏的最优估计值。然后 ,通过最优终点控制理论计算出最优调整值 Aiming at the concrete problems of tensioning of the tied arch bridge, the method of construction control by using Kalman filtering method is discussed. The selected arch axis shape is the object of prediction and control. Kalman filtering method is used to eliminate the random noise mixed in the signal during construction, and the optimal unbiased estimation value in the system statistics is obtained. Then, through the optimal endpoint control theory to calculate the optimal adjustment value
