Impact of Affecting Parameters on Shear Behavior of River Sand

In this research paper, significant parameters that affect the shear behavior of river sand collected from Rishikesh (Uttarakhand) are studied. Classification and geotechnical properties of river sand are found as per standard codes. The effect of the height of fall and time of shaking on the relative density of river sand is found. After that effect of the size of the specimen, relative density and strain rate on shear properties are studied. Relative density is found up to 16 min of vibration with a step increment of 2 min. Direct shear test results of 300 mm and 60 mm shear boxes are compared to study the specimen size impact. The strain rate of 1.25, 0.625 and 0.25 mm/min are considered to analyze the strain rate impact. Three relative densities at 50, 70 and 85% of direct shear test specimens are considered. Relative density becomes constant after a particular point of the fall height and time of vibration. Shear properties of sand are affected significantly by different test scales, strain rates and relative densities of river sand specimens.
