Liquefaction potential of reinforced sand with plastic wastes

Granular soil liquefaction, due to developed pore water pressure during undrained cyclic shear of saturated soils, is regarded as a common phenomenon under earthquakes loading. This results in the huge damage infrastructures. Various reinforcement materials have been successfully implemented with particular attention use waste satisfy design specifications and also reducing adverse environmental effects. paper investigates possibility using plastic fibers material mitigate liquefaction potential generation reinforced sand For this purpose, 42 stress-controlled triaxial tests were conducted on Babolsar sand, by polyethylene terephthalate (PET) polypropylene (PP) fiber contents 0.25%, 0.5% 1%, confining pressures 50, 100 200 kPa, stress ratios (CSR) 0.2 0.35. Results revealed that addition these could significantly increase resistance also, an content, number cycles leading increased. Adding wastes decreased generation, effect was more pronounced content.
