Excess pore pressure generation and post-cyclic loading settlement of geofiber-reinforced sand

Kenan Hazirbaba, Maksat Omarov

Abstract

The response of geofibre-reinforced sand to dynamic loading is investigated in this paper in terms of excess pore pressure generation and post-cyclic load reconsolidation. Strain-controlled, undrained triaxial tests were performed on saturated sand specimens prepared with varying geofibre content. Tape type and fibrillated type polypropylene geofibre were used with Ottawa (C-109) sand at 0.2%, 0.5%, and 1% dosages by dry weight of soil. The tape type geofibre was found to be more effective than the fibrillated type in reducing the excess pore pressure. Both the type and content of geofibre were found to influence the post-loading settlement.
