Özet
<p>Soil improvement methods in geotechnical engineering are comprised of different techniquessuch as compaction, jet grouting. In addition, use of additives in soils to create composite material and toimprove engineering properties is widely used by researchers. In this study, the effect of addingpolypropylene fibers in sandy soils is investigated in terms of shear strength behavior by carrying outconsolidated undrained triaxial compression tests. Samples are prepared with two relative densitiesrepresenting loose sand and dense sand conditions. The amount of fiber content is determined as 0.1%,0.3% and 0.5%. To reflect the effect of overburden, samples are subjected to consolidation pressures of 50,100 and 200 kPa. Results are interpreted in terms of dilative and contractive behavior, stress-strainrelationship, excess pore pressures and undrained effective stress path behavior. </p>
