Liquefaction of Fine Grained Soils


The liquefaction behavior of silts and silt clay mixers was investigated over a range of plasticity index values of interest by conducting cyclic triaxial tests and was compared with that of sand. It was found that saturated silts with plastic fines behave differently from sands both with regard to rate of development of pore water pressure and axial deformations with number of load cycles. The results also showed that liquefaction susceptibility of silts shows a marked change with change in the plasticity index values. For a PI range of 2-4%, the liquefaction resistance of silt was fond to decrease with an increase in plasticity. The results of the investigation were compared with available information and reasonable agreement was noted.
