Abstract

This study presents a Ground Lining Interaction (GLI) model to consider the deterioration of primary supports and realistic ground conditions in evaluations of accurate New Austrian Tunnel Method (NATM) tunnel loads acting on concrete linings. Several parametric studies of the major parameters that influence tunnel loads are performed and the results are compared with Terzaghi's formula. Numerical results demonstrate that the proposed GLI model is capable of reducing excessive tunnel loads by up to 30%. Based on the obtained results, a simplified GLI formula that can be used in engineering practice is proposed for NATM tunnel loads on concrete linings.
