    Abstract

    Fibre-reinforcement has been proposed as a potential solution to increase the liquefaction strength of soils and has shown promise in laboratory element tests. However, the behaviour of fibres and the dynamic properties of the composite of fibres and sand in a non-element boundary value problem still require verification. Two dynamic centrifuge tests have been performed in this study. One test was subject a soil layer of entirely fibre-reinforced sand to an earthquake motion, and the other containing comparable clean sand to act as reference. This work shows that fibre-reinforced sand can be modelled on a centrifuge provided sufficient care is taken in preparation. Fibres are beneficial in enhancing stiffness of sand matrix, but for the free field tests conducted then no obvious improvement in the response of excess pore pressures and ground settlement were observed. It is therefore proposed that the fibre-reinforced sand requires a driving shear stress to mobilize the full effectiveness of the fibre-reinforcement.
