Abstract: In order to accurately control the quality status of bridge and tunnel equipment, formulate scientific maintenance methods and maintenance strategies, and improve the efficiency of bridge and tunnel maintenance operations, based on the work safety production management information system, this paper designed the intelligent terminal App for maintenance operations of railway bridge and tunnel from three aspects: standardized bridge and tunnel disease collection, automatic maintenance evaluation, and intelligent maintenance acceptance. The intelligent terminal App can meet the requirements of timeliness, authenticity and accuracy of field data collection, improve the intelligent disease identification ability, assist in improving the intelligent level of bridge and tunnel maintenance operation, and provide data support for the big data analysis of bridge and tunnel equipment status.
