Liquefaction of Silty Soils

Abstract

Liquefaction during earthquakes has been a significant cause of failure of onshore as well as offshore structures. The phenomenon of liquefaction has been studied extensively for the case of cohesionless soils. Fine- grained soils, such as silts and sands with fines, have generally been considered non-liquefiable in the past. Recent studies have shown that fine-grained soils in certain situations may be susceptible to liquefaction. This paper presents the results of an experimental investigation conducted to determine the liquefaction susceptibility of a low-plasticity silty soil. Cyclic triaxial tests were conducted on undisturbed and reconstituted specimens for this purpose. The results of the study indicate that low-plasticity specimens used in this test program were susceptible to failure by large axial deformations even though liquefaction defined in terms of loss of initial effective confining pressure may not occur.
