Liquefaction Resistance of Solani Sands Under Cyclic Loads

This paper deals with the study of liquefaction resistance of Solani sand using cyclic triaxial tests, which has never been reported in the literature. At present, the most widely used laboratory procedure to evaluate liquefaction resistance of soil deposits is the stress controlled cyclic triaxial tests. A comprehensive experimental program was undertaken in which stress controlled/strain controlled undrained cyclic triaxial tests were performed to measure pore water pressure, volume change, etc. for the Solani sand samples at different cyclic shear strains. This paper presents the liquefaction resistance of Solani sand based on the results of cyclic triaxial tests. The effects of parameters such as relative density, amplitude of cyclic shear strain, confining pressure and frequency of cyclic loading on liquefaction resistance of Solani sand are studied. The variation of cyclic deviator stress with number of cycles has been presented.
