摘要
本文系统地研究了灰色理论在大跨度连续刚构桥线形控制中的运用,通过三种不同的方法建立灰色模型,预测节段施工过程的挠度变化,再利用所得到预测值进行比较分析。首次在桥梁施工控制中运用原始数据序列进行三点滑动平均的方法,有效地减小了数据波动性和人为操作误差的影响,提高了灰色模型的预测精度,其结论可为类似工程提供借鉴。
the use of Gray Theory in long span continuous rigid frame bridge construction control was studied in this paper and calculated program about the Gray Theory used in this thesis .Figured out three gray models in order to predict deflection changes during segments construction, then can utilize these predicted values to work out the elevation of moulding board. slided average method of origin data serials was used in bridge construction control firstly.By using this method, data fluctuation and operation err...
