Development of a Smart-Client Based Bridge Management and Maintenance System for Existing Highway Bridges

The function of road is to provide a safe, economical and effective road network for the movement of people and goods. And an effective bridge management strategy is very important in fulfilling this function. In terms of the demand of current operation and management of the existing highway bridges in our country, the objective and the basic framework of the smart-client based bridge management system is analyzed in this paper. And based on the Smart Client and Dotnet 2.0 frameworks, the Bridge Inspection Rating Maintenance and Management System is developed by employing object-oriented programming technology. Here, the model design of each subsystem is introduced from the following perspectives: smart-client network support, design of central database, bridge management of project-level and network-level. Besides, the latest mathematical method of data mining and artificial intelligence is employed in optimizing decision analysis. Through verification of three long-span bridges of certain expressway, the system achieves the capability of systemizing and programming of the bridge maintenance, and rationally distributing the maintenance fund.
