Steel bridge deck pavement system health monitoring system and method based on acoustic emission technology

Abstract

The invention relates to a steel bridge deck pavement system health monitoring system and method based on an acoustic emission technology. The system comprises a steel bridge deck, a steel bridge deck pavement system installed on the top of the steel bridge deck, and a vehicle load wheel track position installed on the top of the steel bridge deck pavement system. The acoustic emission collecting and processing platform is installed at the bottom of the steel bridge deck, an acoustic emission sensor is installed at one end of the acoustic emission collecting and processing platform, and the acoustic emission sensor is located at the bottom of the steel bridge deck. According to the method, data of strain, deflection, temperature sensors and other traditional methods can be combined, pavement layer state data are deeply excavated and reanalyzed, the data are fully utilized, the steel bridge deck pavement system state can be accurately and effectively evaluated and pre-warned, and the construction period is shortened. The problems that an existing real bridge steel bridge deck pavement monitoring system is single in laying sensor monitoring, high in cost, prone to damage, low in data utilization rate, incapable of achieving real-time analysis and early warning of data and the like can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of bridge health monitoring, in particular to a health monitoring system and method for steel bridge deck pavement systems based on acoustic emission technology. Background technique [0002] With the continuous development of bridge construction in our country, due to the advantages of small steel structure section, light weight, high strength, good ductility, large safety reserve, and good seismic performance, steel structure bridges are used in bridges in new construction and reconstruction projects. The proportion of steel structure bridges has been significantly improved. [0003] The service state of the steel deck pavement system is mainly affected by extreme temperature and traffic conditions. Poor ambient temperature will have a certain impact on the performance of paving materials. In summer, the temperature of the bridge deck is too high, and the high temperature lasts for a long time. Under the...
