AI Technical Summary
In highway reconstruction and expansion projects, the stability assessment of existing structures is easily affected by dynamic loads, and the accuracy and robustness of existing assessment schemes are poor.
A visual analysis-based assessment system is adopted. By acquiring multi-source data and using transfer learning to construct a load-strain mapping model, and combining multi-dimensional processing and analysis of damage data, a three-dimensional damage heat map is generated to realize the location and assessment of the damage area.
It improves the accuracy and early identification rate of damage identification, reduces positioning errors, enables quantitative assessment and accurate decision-making of structural stability, and enhances the real-time performance and robustness of the assessment.
