Effect of particle size distribution on shear strength of soil

Abstract

Soil grain size distribution has a significant impact on the mechanical properties of geotechnical materials. This study presents a laboratory investigation into the effects of fine content and grading factors on shear parameters. A series of shear tests and triaxial tests on sandy soils were performed for this aim. Finally, the outcomes of both strategies were compared and assessed. It was discovered that altering the grain size distribution results in changing the values of shearing parameters. Furthermore, the outcomes of different laboratory tests are not the same.
