摘要
跨海大桥一般与陆地相距较远,利用传统的安全监测手段常常因远离基准点而无法对跨海大桥实施有效监控,针对长大跨海大桥安全监测系统设计的困难,在模拟实验的基础上提出了解决方案——跨海大桥整体安全性自动监测技术,结合东海大桥介绍了跨海大桥整体安全性自动监测技术的实施方法、实施要领与实施注意事项。为适应跨海大桥的动态稳定特征提出并采用了动态基站监测技术,同时还提出并采用了GPS-RTK与测量机器人的集成技术,从而使跨海大桥整体安全性的自动、可靠监测成为可能。
Usually, bay bridges are far away from continents. It is difficulty to monitor the safety of bay bridges by traditional ways, because there is a limit in survey range of ETS （Electronic Total Station） or GPS. A new automatic monitoring way of structures safety of bay bridges by the monitoring technique of dynamic base station is put forward to resolve the difficulty of structures safety monitoring of bay bridges. The new way is based on the bridge monitoring experience and simulated test in the same scale. The new way uses the integrated technique of ETS and GPS-RTK. In this paper, for the example of Donghai Bridge （the overall length more than 32.5 kilometres）, the monitoring process, monitoring essentials and monitoring points for attention of dynamic base station monitoring technique are expounded.
