Weight Correction of Bridge Substructure in Underwater Environment Based on Analytic Hierarchy Process

Year: 2025

Type: article

Abstract: At the structural level, the current evaluation standards do not differentiate between the weights assigned to components of land bridges and underwater bridges. This lack of distinction often results in inaccurately high evaluations of the technical condition of underwater bridges, posing significant safety risks. This paper addresses this issue by employing the Analytic Hierarchy Process (AHP) to develop a hierarchical evaluation model specifically for bridges in underwater environments. The expert judgment matrix is created for the component layers of these bridges. The weights of the sub‐structure component layer and the overall structure layer in underwater conditions are recalculated to enhance the precision of the bridge condition assessments, thereby improving the reliability of the results.
