Analytical Hierarchy Process Based Post-Earthquake Health Diagnosis Method for Tunnel in South of China

In order to evaluate the health condition of the tunnel in South China and give advices on reinforcement and maintenance scheme, a post-earthquake health diagnosis method is presented. After a comprehensive investigation on failure modes of tunnel, a four-level ranking method and a index system for post-earthquake health diagnosis of highway tunnel are proposed. Besides, analytical hierarchy process (AHP) is introduced into for determining the post-earthquake health diagnosis mode. Case study manifests the validity of the proposed method, which can provide valuable guide to the post-earthquake health diagnosis and relief work.
