“Human-Vehicle-Tunnel-Environment” Based Study on Key Issues and Solutions of Operation and Maintenance Risk Evaluation for Urban Road Tunnels

Abstract

This paper provides analyses of operating environment features of urban tunnels in building, traffic, hydrology, vertical alignment, social environment and examination of key issues in operation and maintenance risk evaluation for urban tunnels: diversity and complexity of evaluation factors; timeliness of evaluation result; uncertainty of rating, etc. Relevant countermeasures are proposed for the above-mentioned key issues, including information collection technology based on the Internet of big data technology and risk dynamic assessment and management platform, etc., to provide a solution path for the real-time, intelligent and informatization of urban tunnel risk management and control.
