The analysis and design of urban bridge safety early-warning management system

In this paper, think of it in terms of safety science, it´s pointed out that urban bridge safety early-warning system is mainly composed of four elements: human, bridge, environment and management, by summarizing the research status in the field of bridge security. Then primary configuration of early-warning management system for urban bridge is put forward, which is formed from four subsystems: human factor control subsystem, bridge condition monitoring and forecasting subsystem, bridge accidents emergency disposal subsystem and bridge safety early-warning management system. In order to keep bridge operating safe, enough attention should be given to the research of bridge techniques as well as the efficiency of bridge management. Improvement and supplement of early-warning management system for urban bridge must rely on the theory development and technology progress of safety science, along with accumulation and summary of safety management practices for bridge engineering.
