摘　　要：以重庆黄花园嘉陵江大桥施工控制的具体实践为例， 介绍了该桥施工控制过程中所采用的控制原理和方法． 对于误差分析， 定义受控对象和控制变量， 确定目标函数， 采用了控制论中的随机最优控制理论， 实现了计算机对施工的全过程控制， 使大桥的下游幅顺利合龙．The construction control process of Chongqing Huang hua yuan Jia Lin River bridge is taken as an example in this paper.The control principle and method which used in construction control is stated.The controled object and control variable are defined and objective function is established by stochastic optimal control theory of engineering cybernetics for the error analysis.So the whole construction control is achieved by computer as a measure of joining the two section of a bridge sucessfully.
