ABSTRACT: The cyclic triaxial tests on partially saturated to fully saturated silty-sands were carried out to investigate the effect of saturation on dynamic soil parameter (such as shear modulus and damping ratio). The surface liquefied silty-sand which were erupted to the ground surface due to the 3rd January 2017, Manu earthquake, Tripura, India is used in the present study. Though the earthquake was of moderate magnitude with Mw 5.7, it produced liquefaction in the river bed as well as agricultural farmland adjacent to the Manu River. A constant volume split mold of size 50.1 mm internal diameter and 102 mm height was used in preparing the test specimens. The tests were carried out for two different relative densities (50 %, 30 %) with varying cyclic shear strain amplitudes. The reconstituted soil specimens prepared at partially saturated to fully saturated states were subjected to sinusoidal loading at 1 Hz frequency and results were compared. The same effective confining pressure of 100 kPa was maintained for all the tests specimen.
