A brief demonstration of tutorial 1a of PLAXIS 3D. Large tunnels in soft rock or hard soil are now often constructed using full face excavation associated with ground reinforcements. Such works induce complex interactions between the soil, the reinforcements and existing structures, which are difficult to model precisely. In order to improve the understanding of ground response to this tunnelling method, and to collect precise data for validating numerical models, two comprehensive monitroing sections have
