Quaternity bridge safety and state monitoring system

Abstract

The invention discloses a quaternity bridge safety and state monitoring system comprising a construction monitoring system, a load testing system, a routing-inspection and maintenance system and a state monitoring system. The quaternity bridge safety and state monitoring system can share hardware and software resources, and can be connected with a main engineering and traffic engineering via hardware interfaces and joints. Reference model building, model modification and damage identification can be realized by the aid of whole-process information of construction monitoring, load testing, state monitoring and routing inspection and maintenance. State evaluating can be realized by the aid of results of state monitoring and routing inspection and maintenance, and the quaternity bridge safety and state monitoring system is an automatic and manual, integral and local, qualitative and quantitative, objective and subjective, obscure and clear monitoring and evaluating system and is applicable to the field of bridge engineering.

Description

technical field [0001] The invention belongs to the field of bridge engineering and relates to a four-in-one bridge safety and health monitoring system, in particular to a four-in-one bridge safety and health monitoring system for large complex bridges. Background technique [0002] The investment scale of bridge engineering is large and the service period is long. Due to the coupling effect of unfavorable factors such as quality defects, load effects, environmental erosion, material aging, natural disasters and man-made disasters, it will inevitably lead to structural damage accumulation, resistance attenuation and functional degradation. As a result, the safety, applicability and durability of the bridge are reduced, resulting in frequent maintenance and repairs, and may cause catastrophic accidents in extreme cases. [0003] In order to ensure the reliability of the whole process of construction and operation of large bridges, strengthen the monitoring and evaluation of t...

Problems solved by technology

In the process of design, implementation, maintenance, etc., due to the lack of unified planning, most of the existing systems operate in an independent manner, lacking overall consideration, and have the following shortcomings: (1) Part of the health monitoring system equipment and construction monitoring, load Tests, inspections and maintenance are repeatedly set up, some instruments are inconvenient or cannot be installed after the completion of the main project, and the connection with the traffic project and the main project cannot be considered in advance, resulting in damage and waste

(2) The health monitoring system can only monitor the various responses of the structure during the use phase, but the dead load effect and construction process information that has a huge impact on the structure have been lost. The massive health monitoring data is called "information island"

(3) Due to the inconsistency of software, hardware, data collection, management, identification, and evaluation, it is difficult for the health monitoring system to be substantively integrated with the inspection and maintenance management system, and it is also impossible to effectively integrate construction monitoring and bridge load test information. Limited utility of heavily invested health monitoring systems
