Development and Prospect of Bridge Maintenance Management System in China
This paper reviews the research history and envisions the development trend of the maintenance management system of road bridges in China,aiming to promote the digitization of maintenance and management of road bridges and enhance maintenance efficiency.The three development stages of the bridge maintenance management system are presented,namely the paperless data base management stage,the stage to technically evaluate the methods to improve bridge structural condition and assist maintenance decision making,and the highly-efficient bridge management stage that integrates visualization,patrol terminals and health monitoring system.The function modules of systems in each stage and their characteristics,issues such as what they are used for and what kind of disadvantages they have are summarized.Considering the research hotspots in smart maintenance and management of bridges,the development trend of the smart maintenance management system that targets to reduce the influence of human factors and achieve economic and efficient maintenance is discussed and predicted.As per the analysis,the maintenance management system of road bridges at present can meet the refined management requirements of related authorities,but still has room to improve in terms of smart degree and effective resources allocation.The smart maintenance system that integrates smart sensing,identification,decision making,multiple date sources fusion offers multiple techniques to sense gigantic data of bridges,thus enabling to use big data analysis and data mining to evaluate bridge state,guide the operators to achieve economic and efficient maintenance decision making,and finally realize the smart maintenance of road bridges.
