Summary
In this article, we report on model tests of shallow tunnel in a geotechnical centrifuge. The influence of the overburden on the required face support pressure, ground deformation, failure mechanism and surface settlement is investigated. Owing to small shear strain in pre-failure regime, high spatial resolution is needed in the instrumentation. The experimental results are then compared with the closed form solutions and a finite element analysis.
