EDZ-related phenomena in the Opalinus Clay during the operations phase of the Mont Terri rock laboratory: a damage of the shotcrete liner caused by swelling and creep processes; b dessication cracks at the tunnel wall of the HG-A microtunnel in response to tunnel ventilation; c degradation of the Opalinus Clay caused by water uptake at the contact zone between liner and rock (HG-A microtunnel)
