摘要
在对以往各种斜拉桥误差调整方法分析的基础上,对自适应模块进行了适当简化,保留最优调整模块.提出了以残余误差的平方和最小为目标函数的优化调索方法,并用该法对实桥进行了现场监控.实践证明该方法对主跨400 m左右的叠合梁斜拉桥施工控制有很好的控制效果和较高的计算效率,其优化调整结果可以很好地满足工程需要.
Based on the analysis of all kinds of error adjustment methods, a new method was proposed. The method is based on the aim of minimum square sum of error of main girder elevation and cable force. The self-adaptive method is simplified and the optimum adjustment module is reserved in the method. The method has been applied in a practical cable-stayed bridge construction control. The analysis results show that the method is accurate and effective to composite beam cable-stayed bridge with its main span around 400 m.
