Abstract
China is shifting from the stage of large-scale bridge construction to the stage of equal emphasis on the construction and maintenance of bridges. The problems of low efficiency and high cost in bridge inspection are becoming more and more prominent, which threaten people’s life safety. In this paper, the deterioration state prediction model of concrete beam bridge under Boosting DT C5.0 was established as the basis, and optimization suggestions were put forward in terms of bridge inspection standards and processes, which aims to perfect the bridge inspection mechanism, realize the fine management of the bridge and prolong the service life of the bridge. Research shows that: first, the bridge inspection standard with a single index should be improved into the bridge inspection standard with multiple indexes, so as to scientifically determine the bridges that need to be inspected and optimize the allocation of maintenance resources. Second, the bridge deterioration state prediction model is used to add a screening mechanism for the bridge in the inspection plan, which can effectively reduce the workload of bridge inspection and enhance the inspection efficiency. Third, the deterioration phenomenon of coexistence between adjacent traffic assets should be fully considered and the linkage inspection mechanism of adjacent traffic assets should be established to improve the effect of bridge inspection.
Highlights
Bridges serve as critical structures to the functionality of road networks within an infrastructure system
Based on the prediction model of the deterioration state of concrete beam bridge, this paper puts forward suggestions on the optimization of the inspection mechanism of concrete beam bridge from three aspects of bridge inspection standard, inspection process and inspection content, and proves the feasibility of the suggestions through empirical analysis
This paper uses Artificial Neural Network (ANN), Support Vector Machine (SVM) and Decision Tree (DT) algorithms to predict the deterioration of concrete beam bridge
Summary
Bridges serve as critical structures to the functionality of road networks within an infrastructure system. With the continuous improvement of China’s economic strength, infrastructure construction has been developing rapidly. China has made important breakthroughs in the field of bridge construction technology, which highlights the technical deficiencies of Chinese bridges in the operational stage [1]. Due to the lack of bridge maintenance and management technology, the bridge is prone to structural safety risks, which brings huge hidden dangers to people’s life safety [2, 3]. The focus of bridge engineering in China is changing from construction to maintenance [1]. Bridge inspection is the starting point of bridge maintenance.
