Problems solved by technology

At present, the conversion of bridge deflection based on the change of inclination angle is an indirect calculation method. The deflection value is calculated by the principle of segmental superposition. The calculation errors of different segmental methods are different, resulting in unstable evaluation results and high operating costs.

Abstract

The invention discloses a method for quickly evaluating the normal use state of a bridge. Compared with the traditional static load test, the rapid pre-evaluation system is innovated on the aspects oftest instruments, the number of test points, installation of the test instruments and a test method, aims to reduce time consumption and cost on the premise of ensuring an accurate evaluation result,and is characterized in that the deflection of the bridge under a specific loading position is measured in a high-precision manner through an inclination angle sensor.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a method for quickly evaluating the normal service state of a bridge. Background technique [0002] Bridges are all going through the process of construction, service, functional degradation, and scrapping. During use, as time goes by, under the action of internal or external or natural adverse factors, material aging and structural damage will occur. The accumulation of this damage will lead to structural performance degradation and reduced reliability. In the case of reinforcement, its function will inevitably decline at an accelerated rate. Since bridges are composed of basic materials such as steel and concrete, after statistical analysis, the deterioration of new and in-service bridges has similar laws. It is very important to study and predict the reliability and status of bridges in the future. At present, the conversion of bridge deflection based on the inclination chan...
