Advancing understanding of stress distribution in Composite Tunnel Linings: Insights from case studies using advanced numerical modelling

Composite tunnel linings have been adopted in major tunnel projects such as Crossrail and Thames Tideway. However, understanding and predicting the lining stress distribution between the two layers of linings remains a challenge. This presentation showcases two recent case studies where numerical back analysis and design predictions align closely with in-situ monitoring data and site measurements. These findings highlight the importance of selecting appropriate modelling methodologies, offering enhanced insights into load sharing within composite tunnel linings.
