Effect of Degree of Saturation on Dynamic Properties of Solani Sand in Small Strain

Abstract

This paper comprises of tests conducted on resonant column apparatus (RCA) to find the dynamic soil properties in low strain range for different relative density, confining pressure and the effect of degree of saturation is observed. Sand used for testing is collected from the local Solani River near Roorkee. Dynamic soil properties such as shear modulus, young�s modulus, Poisson�s ratio, and damping ratio. The tests were conducted on a cylindrical samples of diameter 50�mm and height 100�mm. Dynamic soil properties is studied for different relative density (40%, 60% and 80%), confining pressures (100�kPa, 200�kPa and 300�kPa) and degree of saturation (0%, 25%, 50%, 75% and 100%). It has been observed that the shear modulus is decreases with the increase of degree of saturation and damping ratio is increases. � 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
