APPLICATION OF THE REAL-TIME KINEMATIC GLOBAL POSITIONING SYSTEM IN BRIDGE SAFETY MONITORING

A real-time kinematic (RTK) global positioning system (GPS) has been developed and installed on the Humen Bridge (China) for on-line monitoring of bridge deck movement, which may occur as a result of seismic activity, traffic load, and such environmental elements as temperature and wind. This paper presents the main features of the on-line GPS RTK system and its value for on-line safety monitoring. The Humen Bridge is a six-lane highway suspension bridge with a main span of 888 m and a total length of 15.762 km. The GPS RTK system provides all-weather, long-term, and real-time measurement of bridge movement, structure deformation, and spectrum for bridge traffic management and determination of the structural conditions of the bridge. The authors report on the system since its introduction in 2000.
