Regional Bridge Data Extraction and Integration Based on Historical Detection Reports

This study firstly analyses the information source of individual bridge condition evaluation, then expand the analysis from individual bridge to regional bridge-group evaluation, and formulate integration rules for regional inspection, monitoring, traffic volume, and drawings. The integrated data from multi-source information are stored and expressed in the logical form of "route-bridge- component". After data cleaning, a road network database is established, the integrated data is mined for features, and then a comprehensive network level evaluation of regional bridge groups is carried out. The proposed information integration and data mining method and application model can effectively reveal the common characteristics and degradation laws of bridge groups in the road network and can be used for regional bridge network-level assessment.
