A bridge inspection and monitoring integrated health condition assessment system and a use method thereof

Abstract

The invention discloses a bridge inspection and monitoring integrated health condition evaluation system and a use method thereof, belongs to the field of building bridges, and adopts the technical scheme that the bridge inspection and monitoring integrated health condition evaluation system comprises a health monitoring system and an on-site inspection part which are combined for use, and the health monitoring system comprises a data management system, a component rating system and a damage evaluation system; the data management system is used for managing detection data of the sensor systemand a preset database; the component rating system is used for rating importance, danger degree and vulnerability of the bridge components; the damage assessment system is used for assessing the damage assessment state; the on-site inspection portion includes conventional inspection, detailed inspection, and special inspection to evaluate a damage state of the component. The invention also discloses a use method of the system. The system has the advantages that the engineering decisions can be scientifically guided, effective maintenance, repair and reinforcement work can be carried out on thebridge, and the service life of the bridge is prolonged. The method is suitable for the bridge structure detection and monitoring.

Description

technical field [0001] The invention relates to the field of building bridges, in particular to a bridge inspection and monitoring integrated health status assessment system and its application method. Background technique [0002] In order to ensure the smooth flow of bridge traffic, it is extremely important to strengthen the maintenance and management of bridges. The purpose of bridge management is to ensure the reliability of the structure, mainly referring to the bearing capacity, operating status and durability of the structure, so as to meet the predetermined functional requirements. After the bridge is built, due to the influence of climate, corrosion, oxidation or aging and other factors, as well as the long-term static load and live load, it is easy to be damaged, and its strength and stiffness will decrease with time. This will not only affect the safety of driving, but also shorten the service life of the bridge. [0003] The health assessment system of bridge ...

AI Technical Summary

Problems solved by technology

The form is single, the timeliness is low, the terminology of disease description is not standardized, a large amount of data is difficult to share, the retrieval efficiency is low, and the reliability of data statistics is insufficient

Moreover, the work related to the assessment of the impact degree of bridge specific components still relies on the subjective judgment of inspection engineers based on experience and theoretical literacy, which cannot detect the internal dynamic parameters of the bridge structure, and the local structural conditions cannot determine the overall health trend of the bridge; It is impossible to detect the problems and faults caused by the structural changes of the internal structure of the bridge during operation, and it is difficult to reflect the technical condition of the bridge that is most in line with the objective reality
