New Test Methodology for Estimating the Abrasiveness of Soils for TBM Tunnelling
Abstract
Tunnel excavation using TBMs has become increasingly common in recent years, despite the fact that precise evaluation of certain risks has not kept pace with their use. One of the risks easily overlooked is the effect of abrasive ground on cost and schedule. Several test methods exist for rock, but there is limited knowledge of the impact of abrasive soil on soft ground TBMs.
