摘　　要：以京珠高速公路蔡甸汉江公路大桥为例 ,分析了施工过程中主要工艺参数的控制技术。用人工神经网络误差调整理论控制施工预拱度 ,通过测试信息进行参数识别 ,调整和修正有限元计算参数 ,借助应变测量 ,分析了实际结构的真实应力 ,使桥梁的施工质量处于受控状态 。This paper instances Caidian Han river bridge on Jingzhu expressway, analyzes some control techniques of main technology parameters during construction of the bridge. Camber is controlled by error modification theory of neural network. Parameters are identified by the information of measurement, parameters in calculation of finite element are adjusted and modified, by means of strain gauging and stress analysis, the true stress of the actual structure is known. Construction quality of bridge is controlled within the extent of design.Its construction control is meaningful for identical type of bridge.
