Interfacial behaviour in Tunnel engineering

05 November 2021, Version 1
Working Paper

Abstract

The force imparted on the soil by a tunnel boring machine can lead to catastrophic tunnel collapse. To help predict this behaviour the machine is modelled as point source in an elastic/plastic idealized soil with no cohesion. The model predicts a wedge shaped region of plasticity extending from the machine. Within this region of plasticity a reduced hyperbolic flow problem determines the dynamics of the soil.
