ABSTRACT
Structural safety evaluation of tunnels is the basis for reflecting the structural health status of tunnels and adopting reasonable and effective maintenance and repair measures. Based on the analysis of fully automated monitoring data of the structural health of shield method highway tunnels, this thesis conducts a systematic study of the structural health of shield method tunnels, innovatively forms a real-time evaluation index system and discrimination criteria for the structural health of shield method tunnels, and establishes a fuzzy comprehensive evaluation model for the safety state of tunnel structures. A highway tunnel is used as a case study for relevant data analysis and application of structural health and safety evaluation methods to provide important theoretical reference and technical support for solving the practical needs of real-time structural health evaluation and engineering operation and maintenance of shield method tunnels.
