Abstract

The research concerns the effects of a Forepoling Umbrella System (FUS) that comprises steel pipes installed in a canopy shape above a tunnel heading to reduce ground movements induced by tunnelling. As an in tunnel reinforcement measure, FUS is known to be beneficial in reducing soil deformations at source and has been used in a number of projects. An extensive literature review was provided covering the framework of tunnelling-induced soil movements and current understanding of the FUS. That highlighted deficiencies in how key parameters of a FUS can be combined to produce effective support. The aim of the research was to investigate the relative effect of the system parameters to gain a clearer insight into achieving an optimal design of a FUS.
