Problems solved by technology

[0003] The existing indirect detection method based on vehicle-bridge coupling places the acceleration sensor on the wheel of the vehicle passing the bridge, and extracts the dynamic characteristics of the bridge structure from the dynamic response information of the vehicle wheel to identify the damage degree of the bridge structure. However, the installation The acceleration sensor on the wheel is prone to damage, and it is not easy to repair and replace, which affects the normal bridge damage detection, making this method difficult to promote

Abstract

The embodiment of the application discloses a method for quickly detecting damage to a bridge and related devices. Through the embodiment of the application, the bridge is tested for damage based on the vehicle body vibration response data and preset evaluation conditions of the vehicle passing the bridge. The response data is easier to obtain and maintenance is convenient. Therefore, it can effectively improve the speed and portability of the bridge indirect damage identification method.

Description

technical field [0001] The present application relates to the technical field of bridges, in particular to a method for quickly detecting bridge damage and related devices. Background technique [0002] Bridge damage detection refers to the use of on-site non-destructive sensing technology to achieve the purpose of detecting structural damage or degradation through the analysis of structural system characteristics including structural response, and provide reference for the use and maintenance of structures. [0003] The existing indirect detection method based on vehicle-bridge coupling places the acceleration sensor on the wheel of the vehicle passing the bridge, and extracts the dynamic characteristics of the bridge structure from the dynamic response information of the vehicle wheel to identify the damage degree of the bridge structure. However, the installation The acceleration sensor on the wheel is prone to damage, and it is not easy to repair and replace, which affec...
