Research Of Operation Monitoring And Alarming System For Concrete Filled Steel Tube Arch Bridge

Being the junction and throttle of roads, bridge has an important role in transportation, so how to manage bridge validly is the key to ensure smooth transportation. At present, manual inspection, manual collection and manual analysis are widely used for inspection and assessment of bridge. However, these traditional methods have many disadvantages for bridge management, such as low speed, low efficiency, no in time indication for the damaged bridge.For important bridges, inspection monitoring system, which monitors the history of load condition, performance changes, fault emergence and defect development of bridges, is able to assess the real-time operational condition and fault degree. With these real and valid data measured, the monitoring system provides a foundation for time choice of bridge reinforce and adoption of scientific strengthen measure.Furthermore,through monitoring and assessing of bridge structure, give warning signal when unusual climate or transportation or bridge structure condition happen, and provide foundation and guidance for maintenance and management of bridges. It is also concerned by people.There are differences between different kinds of bridges when setting up bridge operation monitoring system.The paper researches on monitoring system for concrete-filled steel tubular through arch bridge.The paper first makes a brief introduction of the establishment of monitoring and performance assessing system for concrete-filled steel tubular through arch bridge, then develops the system software. The paper mainly includes the following:A brief introduction of the entire system;Customer requirement analysis for operation monitoring and performance assessing system for concrete-filled steel tubular through arch bridge;Design for operation monitoring and performance assessing system for concrete filled steel tube though arch bridge;...
