  The major factors affecting tunnel stability include the ground conditions, in-situ stresses, and project-related features. In this research work, critical strain, stress reduction factor (SRF), and capacity diagrams are used for tunnel stability analysis. For this purpose, eighteen tunnel sections are ...  Read More

Analytical analysis of ultimate ground pressure on tunnel support system

R. Rahmannejad; A. Kargar; V. Maazallahi; E. Ghotbi-Ravandi

Volume 6, Issue 2 , July 2015, , Pages 151-157


  The ground reaction curve (GRC) is a vital component of the convergence-confinement method, which possesses many applications in the underground space designs. It defines a relation between the tunnel wall deformations and the ground pressure acting on the tunnel walls. Generally, GRC includes descending ...  Read More
