Abstract : 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 an alysis . so the whole construction control is achieved by computer as a measure of joining the two section of a bridge sucessfully 文摘: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
