阐述了海上地锚式悬索桥主缆索股施工控制中的主要技术特点,包对温度与跨度影响进行分析;并结合海上施工的特点,运用2种测量方法相结合的方式,对基准索股绝对垂度进行测量。介绍了大桥主缆索股垂度调整过程中的施工方法。实践结果表明,控制方法适合施工需要,具有较高的精度,可供类似桥梁参考。
The main technical features in the construction control of the main cable strands of offshore ground-based suspension bridge are expounded, and the influence of temperature and span is analyzed. Based on the characteristics of offshore construction, two methods are combined to determine the absolute value Degree of measurement. The construction method of adjusting the main cable’s dip of bridge is introduced. The practical results show that the control method is suitable for the construction needs, with high accuracy, for similar bridge reference.
