What is Tunnel Opening Shapes and Stability Analysis about?

This document discusses a finite element analysis that models different shapes of underground tunnel openings, including circular, oval, rectangular, and horseshoe shapes. The analysis aims to understand the impact of opening shape on tunnel stability by examining stresses, strains, and deformations in the surrounding rock mass. An oval opening shape was found to result in the lowest deformations at the crown of the opening, while a horseshoe shape, commonly used, resulted in somewhat higher distortions com
