1. Data Collection: The detection target is bridges; the detected performance type is durability performance; electrochemical signals and steel bar samples of in-service bridges are collected. 2. Data Processing: Based on the collected electrochemical signals and steel bar samples, the finite element technique is adopted to establish the relationship model between electrochemical detection signals and mechanical properties; a time-varying model of electrochemical signals-deformation degree-residual service life that conforms to the boundary conditions of actual bridges is constructed; based on the established time-varying model of electrochemical signals-deformation degree-residual service life, failure chromatography specimens of corroded steel bars are prepared, and the durability performance of bridges can be obtained through comparison. A bridge durability detection process dataset is generated, which includes collection targets, collection locations of electrochemical signals, collection time, data for finite element model construction, data for time-varying model construction, data of corroded steel bar failure chromatography specimens, and bridge durability evaluation values, etc. 3. Data Application: This dataset can be used for bridge durability detection in China, to conduct timely and accurate assessment and prediction of the health status of bridge structures, and provide expert-level management and maintenance decision-making plans for abnormalities and disease damages of bridge structure health status. It has strong applicability, good reliability, and is convenient for popularization and application.
