Application of Improved Random Subspace Algorithm in Bridge Overall Risk Assessment System

Bridges are the control hubs on transportation lines, and how to ensure their safe and reliable operation is a very practical issue. This article analyzes the safety risks of bridge construction and provides a modified model suitable for the evaluation of safety risks in large-scale bridge construction. The improved random subspace algorithm is used to incorporate management factors into the evaluation process, which can better reflect the impact of management factors on actual projects. At the same time, this article further improves the random subspace algorithm to improve the scientificity and accuracy of the evaluation results. In the case of traditional algorithms, low risk accounts for 66.1%, while in the case of improved random subspace algorithms, low risk accounts for 74.1%. This article improves the application of random subspace algorithm to reduce potential risks during construction and reduce the incidence of bridge construction accidents.
