摘要
跨海大桥大多远离陆地,由于电子全站仪、GPS测程的限制,传统大桥形变监测手段常因远离基准点而无法对跨海大桥实施有效监控.针对长大跨海大桥形变监测的困难性,提出了跨海大桥结构形变监测的动态基站自动监测技术,动态基站自动监测技术的核心是电子全站仪与GPS-RTK技术的有机集成.结合实例阐述了跨海大桥动态基站自动监测技术的实施方法、实施要领与实施注意事项.
Many sea-crossing bridges are far away from continent. It is difficulty to monitor their structural deformation by traditional way because there is a limit in survey range of ETS （electronic total station） or GPS. The dynamic base-station monitoring technique of structural deformation of seacrossing bridges is put forward to overcome the difficulty. The new way uses the integrated technique of ETS and GPS-RTK. The monitoring process, monitoring essentials and monitoring points for adopting dynamic base-station monitoring technique are expounded with an example.
