An Intelligent Bridge Management and Maintenance Model Using BIM Technology

Abstract

In recent years, the bridge construction industry of China has developed rapidly. With the increase in bridge service lifetime, numerous damages and cracks have appeared that pose a direct threat to its structure and transportation safety. Therefore, a new approach to bridge management and maintenance is proposed using building information modeling (BIM) system. The objective of this paper is to monitor and manage bridge problems in real time. It will develop an intelligent bridge management and maintenance system model. This system will improve bridge management and maintenance and reduce the number of accidents on unsafe bridges. According to the data, the management and maintenance units can adopt scientific and reasonable methods to manage and restore bridges. This will ensure the safety and property of people. To improve the efficiency of bridge management and maintenance, a visible and accurate model is built with a combination of BIM technology. In this model, bridge damages are controlled and analyzed using BIM technology. The results show that the changes in the cracks and damage to the bridge within a year continue to rise from January to September and decrease from September to October. The crack of width and length continues to increase from October to December. As a case study, Tianyuan Bridge is selected to evaluate the technical condition of the bridge. The overall evaluation of the bridge result indicates a class II bridge.
