Study On The System Of Health Management Of Active Road Bridge

In China,there are three types of transportation: land transportation,water transport and air transport.Among them,through the bridge to transport belong to land transport,and the pressure is the largest,so to ensure the safety and usability of the bridge can ease the traffic pressure.At present,with the development of the transportation industry,People on the use requirements of roads and bridges are getting higher and higher,not only to safe,fast,but also the road is smooth and comfortable.Therefore,in order to make the road bridge better for people to serve,not only need to carry out regular analysis of the health status of road bridges,it is also necessary to maintain unhealthy bridges in a timely manner to improve the service life of the bridge.The paper through the discussion of human health,leads to the health of the bridge,it analyzes the various influencing factors in the design,construction and use of the northwest highway bridge,and on this basis,carry on the health management of highway bridge.And according to the implementation steps of health management to analyzes and designs the bridge health management information system,to achieve the function of health management information system.The following is the result of the study:(1)The main factors influencing the health of road bridges are discussed,and from the three stages of exploration design,construction and maintenance to analyzes the bridge health problems.Combined with the existing data and the relevant assessment data,given the health rating criteria.(2)Health management is a recurring management process.The paper gives three steps of bridge health management,according to these three steps,the framework model of road bridge health management information system is established.This system includes three parts:bridge basic information,bridge health assessment and bridge health rehabilitation plan.The article has made a basic description and detailed analysis of the functions of each module in this system.The key is the health assessment,first establish a health evaluation system,define health assessment indicators,and then evaluate the various levels,finally gather the results to get a comprehensive health assessment.In addition to the development of bridge health recovery plan,according to the results of the judgments,investigate the information,develop appropriate measures.(3)Analyzed the functions that the bridge health management information system should have,and achieved the functions of the bridge health management information system by Visual Basic program,making this application can carry out relation services for the bridge health management.(4)According to the northwest road bridge survey data,using the bridge informationsystem to carry out its health evaluation,geted the health level of the bridge,developed a corresponding recovery plan,and make the northwest road bridge health management intuitively and effectively reflected.
