EVALUATION OF LIQUEFACTION STRENGTH OF SANDS CONTAINING FINES BY MINIATURE CONE PENETRATION TESTS IN TRIAXIAL SPECIMENS

Abstract

A series of innovative miniature cone penetration tests and subsequent cyclic undrained triaxial tests were performed on sand materials with different fines content and different relative density. Accoding to the cone penetration tests and cyclic undrained triaxial tests, cone resistance and liquefaction strength of sand containing fines considerably reduce as the fines content increase from 0% to 20%. On the other hand, it has been found that one unique curve relating cone resistance with liquefaction strength can be established irrespective of relative density and fines content.
