Research On Preventive Maintenance System Of Concrete Bridge

With the rapid development of the transportation enterprise, bridge as the throat of thetraffic, plays more and more important role.Concrete because of its good durability and highcomprehensive strength characteristics, widely used in bridge engineering. With the increaseof traffic volume, the increasing number of bridge collapse, To bridge maintenance personnelof the enormous pressure. The original maintenance way can not completely meet therequirements of bridge, The most effective way to change the current passive situation is toadopt preventive maintenance. Implement preventive maintenance of bridge to reducemaintenance cost, prolong the service life of bridge, slow down the deterioration rate ofservice performance, has an important significance.This article from the preventive maintenance work, and combining with the status ofconcrete bridge, the preventive maintenance system are studied. This paper firstly combiningwith the development and present situation of domestic bridge, and the situation of studyingon prevention at home and abroad, this paper analyzes the bridge preventive maintenance,obtains the basic concept of bridge preventive maintenance, summaries the contents andrequirements of bridge preventive maintenance, summarizes the characteristics of bridgepreventive maintenance, analyzes the bridge preventive maintenance technology. Secondly,on the basis of concrete bridge defects, for a various of diseases situation, in life-cycle ofbridge to take the preventive maintenance measures. Once again，According to the bridgeinspection data, determine the bridge technical condition. Finally，From the establishment ofscientific and reasonable organization, improve database, and paying attention to the humanresources, to ensure safety and quality qualified of bridge to establish preventive maintenanceof concrete bridge. Preventive maintenance system can provide reference for design andconstruction, convenient bridge maintenance management work, promote the furtherdevelopment of the cause of bridge.
