Abstract

The invention provides a bridge structure monitoring system. The bridge structure monitoring system comprises a sensing subsystem for monitoring responses of a bridge under various external excitations by use of a user or a test instrument; a signal acquisition and processing subsystem used for processing various monitored information and then performing diagnosing; and a health state and safety evaluation subsystem used for analyzing a damage condition of a bridge structure and evaluating a health state of the bridge. The bridge structure monitoring system can analyze the safety status of the bridge structure and evaluate static and dynamic loading capabilities of the bridge structure and the safety and reliability of the structure, thereby providing a scientific basis for bridge management and maintenance decision-making.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a bridge structure monitoring system. Background technique [0002] Transportation is the economic lifeline of a country, and bridges are the throat of traffic. The construction and maintenance of bridges is an important part of a country's infrastructure construction, and it is also a symbol of economic development and technological progress. With the introduction of prestressing technology in the 20th century and the maturity of key bridge technology, breakthroughs have been made in bridge engineering construction. There are more and more long-span bridges at home and abroad. For example, the Akashi-akyo suspension bridge with a span of 1990n was built in Japan. The United States built the famous Chesapeake Bay Bridge across the bay, and the Wuhu Yangtze River Bridge built in my country in 1999 is the largest highway and railway dual-purpose bridge in Asia. The successful construction of ...
