Indian geotechnical journalSummary: Earthquake disasters in seismically active zones revealed the phenomenon of liquefaction which plays a key role in monitoring its severity. Liquefaction affects the stability of the soil by reducing the effective stress which makes soil flows like a liquid. Cohesionless soils under undrained conditions are highly vulnerable to liquefaction, whose effect will be added if it is nearer to the river basin. The present paper investigates the performance of Gangetic sand obtained from the Indo-Gangetic River basin by examining its static and dynamic behavior using triaxial tests. Static as well as cyclic trials were extended for similar three confining pressures and two different densities. The static behavior of the Gangetic Sand was examined on the basis of stress–strain, effective stress path, and pore pressure generation. In addition to the above, the evolution of cyclic stress ratio and dynamic properties including degradation of shear modulus and damping coefficient were analysed while assessing the cyclic behavior. The effect of loading conditions, density, pressures, state of the soil, and stress history were also explored in the current paper.

Earthquake disasters in seismically active zones revealed the phenomenon of liquefaction which plays a key role in monitoring its severity. Liquefaction affects the stability of the soil by reducing the effective stress which makes soil flows like a liquid. Cohesionless soils under undrained conditions are highly vulnerable to liquefaction, whose effect will be added if it is nearer to the river basin. The present paper investigates the performance of Gangetic sand obtained from the Indo-Gangetic River basin by examining its static and dynamic behavior using triaxial tests. Static as well as cyclic trials were extended for similar three confining pressures and two different densities. The static behavior of the Gangetic Sand was examined on the basis of stress–strain, effective stress path, and pore pressure generation. In addition to the above, the evolution of cyclic stress ratio and dynamic properties including degradation of shear modulus and damping coefficient were analysed while assessing the cyclic behavior. The effect of loading conditions, density, pressures, state of the soil, and stress history were also explored in the current paper.
