Abstract

Highlights: A state of art approach to evaluate the elliptical tunnel stability of Hoek–Brown rock mass. Rigorous upper bound and lower bound solutions of elliptical tunnel stability are derived using advanced finite element limit analysis. Comprehensive design tables and equations are proposed for stability evaluation.
