Embodiment 1

[0047] Embodiment 1: A bridge inspection and monitoring integrated health status assessment system, such as figure 1As shown, it includes the combined health monitoring system and on-site inspection. Specifically, the health monitoring system includes a data management system, a component rating system and a damage assessment system. The data management system is used to manage the detection data of the sensor system and the preset database. Among them, the detection data include load, environment detection, static and dynamic response detection and bridge characteristic detection. The component rating system is used to rate the importance, danger and vulnerability of bridge components. The damage assessment system is used to evaluate the damage assessment status, wherein the damage assessment status includes structural damage and non-structural damage, and structural damage is divided into overall damage and local damage, including buckling, cracking, corrosion and degradati...

Embodiment 2

[0054] Embodiment 2: a method for using a bridge inspection and monitoring integrated health status assessment system, such as figure 2 shown, including the following steps:

[0055] First, on-site inspection: conduct geometric appearance inspection and component inspection, conduct damage assessment and analysis, and judge whether it is structural damage, mainly for local areas of bridge components;

[0056] Second, real-time monitoring of the health monitoring system:

[0057] S1: Establish a bridge state database, preset reference values, limit values ​​and finite element models; among them, collect data through sensor systems to form a dynamic database, and then perform preprocessing, secondary preprocessing and postprocessing on the data for data compression, Information extraction and fusion can obtain real-time results about structural characteristics and load response characteristics, and on this basis, a bridge "health" state database can be established, including b...

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 ...
