特大型桥梁施工测量从施工控制网的建立、观测与数据处理,到桥梁基础和上部结构的施工放样与检测,钢梁拼装过程中的形态测控等贯穿于桥梁整个建设过程,因此测量工作时桥梁施工的重要组成部分。因斜拉桥结构和施工工艺复杂、周期长、质量要求高,对测量人员、测量仪器精度、测量方法、数据处理、梁段形态测控方法与措施等提出了很高的要求。
Construction of super-large bridge construction from the construction control network, observation and data processing, to the bridge foundation and the superstructure of the construction and setting out the detection of the shape of the steel beam assembly process control throughout the bridge throughout the construction process, so measuring the bridge An important part of construction. Due to the complicated structure and construction process of the cable-stayed bridge, long period and high quality requirements, high requirements are placed on the measurement personnel, the precision of measurement instruments, the measurement methods, the data processing, the methods and measures for beam profile measurement and control.
