Experimental Studies on Liquefaction Susceptibility and Effect of Fines (Silt) Using Shake Table Test

Abstract

Soil liquefaction is a major reason of failure of foundations of buildings and infrastructure during earthquakedue to loss of shear strength of soil. Liquefaction resistance prediction of soil is one of important aspect ofpracticing geotechnical earthquake engineering. An attempt was made herein to evaluate liquefaction resistanceof saturated sand under varying cyclic frequencies and acceleration. The tests on saturated sand sample andsaturated sand with varying % fines (silt) sample were performed by Shake table. Results of experimentalstudies shows, as increases base frequency and acceleration resulted increases liquefaction potential. Thevariation in pore pressure is obtained for varying percentage of silt contents shows that time required forachieving pore pressure value increases with increasing silt content.
