What is SRH System for SSH Ground Tunneling about?

This document proposes a new system called Stress Release Hole (SRH) System as a substitution for conventional yield support systems for tunneling in squeezing, swelling, and heaving (SSH) ground conditions. The SRH System involves drilling 100+ mm diameter holes without casing in a square pattern around the tunnel periphery to release stresses and control deformation.
