摘要
针对虎门悬索桥上部构造施工流程 ,系统介绍悬索桥上部构造施工监测与控制技术。提出的结构参数现场试验测定方法 ,主缆和加劲梁线型、索塔塔顶变位等监测技术 ,结构参数系统识别和施工控制分析方法 ,以及研制的 3套悬索桥上部构造施工结构分析程序 ,均已在实桥上得以应用 。
This paper introduces suspension bridge's superstructure construction supervision and control technology, based on the practical Humen Bridge engineering project. The test method to get structure parameters on the construction work site is proposed together with the main cable and stiffening girder measuring technology, system identification of structure parameter, and the construction control analysis technology, as well as three sets of structure analysis programs for suspension bridge superstructure, which have been in practical use with good effects.
