The Application And Research Of Maintenance And Management System In Low Grade Highway Bridge In Mountain

This article in to present situation analysis of the mountainous area low grade highway bridge maintenance management as well as to the domestic and foreign bridge management system management system research foundation in, further launches to the mountainous area low grade highway bridge maintenance management system management system applied research. The article mainly introduces this four systems of data management, bridges evaluation maintain policy and architecture and a combination of the actual cases analysed to confirm the theory and method is correct.Firstly, the article analysis the current condition of mountain bridge data collection, and put forward some suggestions for improvement and implementation on this base. Meanwhile, for the convenience of data archivement and with the habit of bridge maintenance , we will prepare three types of checking card, bridges'foundation information card, bridges'routine examination information card and bridges'special examination information card , and propose corresponding inspection cycle and the note as well. Secondly, we will evaluation of bridge condition and given the appropriate score according to the bridge data and the use of DER&U evaluation. The score includes the contents of the various components of the defect in the bridge and the bridge overall performance rating score. As the wholly evaluation score of the bridge, we make it through the ranking methods to determine the road network in the maintenance of order in many bridges. Then, in the system database and the bridge maintenance program, we select the appropriate maintenance program in the project, but the ratio should be selected through the program to determine the final maintenance program. Finally, we will prove that the above method and theory is available with the maintenance of Ren River Bridge case analysis . In addition this paper will classify the maintenance and management system of mountain highway and bridge in network-level bridge management system,,and put forward the basic idea of building for it.
