Safety assessment system for bridge structure based on vehicle load

Abstract

The invention discloses a safety assessment system for a bridge structure based on a vehicle load. The system comprises a monitoring center server and field monitoring equipment; the field monitoringequipment transmits monitored weight information, license plate information and video information of a vehicle passing a bridge and parameter response data of all key points of the bridge structure tothe monitoring center server, the monitoring center server determines the traveling track, traveling speed and weight of the vehicle when the vehicle passes the bridge by comprehensively analyzing and processing the data transmitted by field monitoring equipment, generates prewarning information according to a magnitude relationship between the parameter response data of all the key points of thebridge structure and preset threshold values of the data when the vehicle passes the bridge, and generates a score report of the state of the bridge structure by combining an evaluation strategy. Inthis way, through the safety assessment system for the bridge structure based on the vehicle load, an obtained evaluation result is more accurate and more accords with the actual situation, and bridgesafety operation can be guaranteed better by making the obtained evaluation result as a decision-making basis of a bridge maintenance strategy.

Description

technical field [0001] The invention relates to a bridge structure safety evaluation system, in particular to a bridge structure safety evaluation system based on vehicle loads. Background technique [0002] With the development of the economy and the development of the logistics industry, the road traffic flow has increased sharply, and the phenomenon of overloaded vehicles crossing the bridge has become increasingly serious. Excessive traffic flow and overloaded vehicles exceeding the bridge's bearing capacity will cause serious damage to bridge components. , affecting the safe operation of the bridge structure, which has a major impact on the maintenance and management of the bridge, and even causes major safety accidents such as bridge collapse. [0003] In the Ministry of Housing and Urban-Rural Development's "Technical Regulations for Building and Bridge Structure Monitoring" GB50982-2014 and the Ministry of Communications' "Technical Regulations for Highway and Bridge...

AI Technical Summary

Problems solved by technology

However, in practice, many bridge monitoring systems have not yet installed vehicle load dynamic monitoring equipment. Even bridge monitoring systems that have installed vehicle load dynamic monitoring equipment have not combined vehicle load information with bridge structure monitoring parameters, and cannot evaluate the long-term impact of vehicles. The impact of load on the bridge structure, let alone the adverse effect of overloaded vehicles on the safety of the bridge structure
