THE BEHAVIOUR OF "BUBBLE" MODELS IN TUNNELLING PROBLEMS

This paper compares finite element predictions of the behaviour of two tunnels of the Jubilee Line Extension in London Clay with the field data. One prediction is obtained by modelling the soil as a simple Mohr-Coulomb material, combined with a small strain non-linear elastic pre-failure model. The other predictions are obtained using kinematic yield surface or "bubble" models, which can not only simulate non-linearity, but also plasticity pre-failure.
