About this document
Principal Stress Impact on Tunnel Stability by bistsushant is a document available to read on EtoBox.
This document discusses a study on the effect of principal stress orientation on tunnel stability. Square tunnel model specimens made of cement mortar and sandstone were tested under various principal stress orientations. Three types of models were studied: 1) Regular tunnels under different principal stress orientations. 2) Tunnels with radial cracks in the spandrel under compression. 3) Tunnels with a fixed radial crack under various principal stress orientations. Stress intensity factors of cracks were c
