Abstract
State-of-the-art shield tunnelling in difficult ground conditions still involves a trial-and-error approach as a complete understanding of the physics governing the interaction between the Tunnel Boring Machine (TBM)-shield and the surrounding soil is still lacking. This is particularly concerning as it was demonstrated that the shield–soil interaction, and especially the ground displacement around the shield periphery, gives a significant contribution to the overall soil deformation. This paper quantifies the radial soil displacements induced by a TBM-shield driving in soft ground. The displacements have been obtained by means of a model that captures several aspects of the kinematic behaviour of a TBM, based on theoretical and geometrical considerations. The theoretical model has been verified against TBM monitoring data obtained during the construction of the Hubertus Tunnel, a double-tube road tunnel located in The Hague, The Netherlands. Results show the amplitude and spatial distribution of the ground displacement around the shield periphery as they occurred in practice.
