摘要
运用工程控制论的思想， 将预应力连续刚构桥的施工控制视为一随机最优控制问题， 建立相应的数学模型、目标函数及物理模型， 采用卡尔曼最优一步预测， 按确定性的最优控制规律构成闭环状态反馈系统． 同时， 在现场建立计算机工作站， 使计算机对各施工阶段进行调整控制，达到控制的目的． 其成果已在重庆黄花园嘉陵江大桥的施工控制中得到了应用．
In this paper,the construction control for prestressed continuous rigid frame bridge is regarded as a stochastic optimal control problem which based on the engineering cybernetics concept.The mathematical model、objective function and physical model is established first,and the closed loop feedback control system is formed by means of the Kalmans filtering method according to the deterministic optimal control.At the same time,different construction stage is adjusted by computer work station which established on the spot,and the control goal is achieved successfully.The result is used in construction control of Chongqing Huanghuayuan Jialin river bridge.
