摘要
系统介绍了马水河特大桥悬臂浇筑施工监测误差分析、箱梁预拱度预测和调整,保证成桥后桥面线形、合龙段两悬臂端标高的相对偏差不大于规定值,为大桥安全顺利建成提供技术保障。
This paper systematically introduces monitoring error analysis and forecasting of the cantilever pouring construction of Mashuihe River Bridge, and adjusts the elevation of the next vertical template, to ensure that the bridge line type and the relative deviation of elevations of the two cantilevered end in the closure section are not more than the specified value after the completion of the bridge, thus providing technical support for the safe completion of the bridge.
