What is Numerical Modelling of Tunnel Lining about?

This document discusses numerical modeling of segmental tunnel lining. It presents the following: 1) Current analytical methods for designing segmental tunnel lining have simplifications and do not fully consider joints, leading to overconservative results. 2) A finite difference method (FLAC2D) is used to model segmental lining by reducing the bending stiffness at joint locations. Sensitivity analysis is performed to select a model where bending moments at joints are close to zero. 3) As a case study,
