The Shear Strength Behaviour of Yamuna Sand-A preliminary study

Abstract To describe the strength parameter in the loaded soil mass are the cohesion and internal frictional angle of the soil. The shear strength determination to study the shear strength after tillage a schematic study on Yamuna sand is conducted. Yamuna sand which is present in the banks of river Yamuna in around Delhi is taken for this study. The shear strength behaviour of Yamuna sand was tested through triaxial and direct shear. For this consolidated drained triaxial test (CD) was conducted on Yamuna sand and results are very different from direct shear test results. The angle of internal friction is more in CD triaxial test as compared to direct shear test. Also some cohesive strength is also find in CD triaxial test which was not found in Direct Shear Test (DST). Direct shear test was conducted for dense and loose state of relative density and saturated state of Yamuna sand. The angle of internal friction was found to be highest in saturated state for Yamuna sand. Among dense and loose, dense state giving higher internal angle of friction.
