A METHOD FOR ASSESSING THE QUALITATIVE STATE OF BRIDGES BASED ON A QUALIMETRIC MODEL

Abstract

The article presents the application of a method for assessing the qualitative state of bridges based on the use of qualimetry methods. The proposed approach considers a wide range of parameters that affect the functioning and reliability of road bridges. The method involves the use of a qualimetric model that allows systematizing and structuring of information about the physical condition of individual bridge elements and functional indicators. The weighting of the parameters was determined using expert and estimated methods, which increased the accuracy and objectivity of the assessment. The development of a qualitative condition model includes the following stages: identification of bridge elements, determination of assessment parameters, development of a qualimetric model, determination of weighting coefficients for each criterion, analysis of the results of a specific object inspection, and determination of the overall operational condition of the bridge. The results of the study show that the proposed methodology can be effectively used to assess the condition of bridges, providing a sufficiently high accuracy and completeness of the assessment. This contributes to improving the safety and reliability of bridge structures, reducing accidents and optimizing their maintenance costs. The proposed assessment method has prospects for implementation in the practice of bridge condition management and can be further applied in the system of monitoring the condition of transport facilities.
