What is Rock as Tunnel Construction Material about?

This document discusses rock as a construction material for tunnels. It investigates fracturing of intact rock, jointed rock, lessons from two dramatic tunnel failures, and tunneling through faulted rock. Intact rock may experience tensile cracking next to the tunnel from lateral strain, even when stresses are compressive. This cracking is caused by exceeding the critical extension strain of the rock.
