| Abstract: |
The Sutong Bridge being currently constructed in Jiangsu Province, China, is the world’s longest cable-stayed bridge with a main span of 1088 m. With the purpose of securing the operational and structural safety of the bridge throughout its 100-year life span and facilitating the bridge inspection and maintenance, a sophisticated long-term structural health monitoring system, called Structural Health Monitoring and Safety Evaluation System, has been devised and is being implemented in synchronism with the bridge erection progress. This paper outlines technology achievements in the research and design of this monitoring system through exploring its five modules: (i) sensory system (SS); (ii) data acquisition and transmission system (DATS); (iii) data processing and control system (DPCS); (iv) structural health evaluation system (SHES); and (v) portable data acquisition system (PDAS). |
