When during tunnelling the shield advances forward, grout mortar is applied to fill the gap between the excavated suface and the extrados of the tunnel lining. The grout is sometimes intruded and hardened up in the shield tail and it might cause difficulty in controlling the shield tunnelling performance. Therefore, the aim of this study is to examine the influence of the intrusion the grout on the shield tunnelling performance. This study examines the behaviour of the articulated shield during excavation a curved aligment. The simulation results revealed that the intrusiion of the grout material into the shield tail is one of the factors affecting the shield behaviour during excavation.
