There are difficulties in conducting laboratory tests as reconstituted models can often be misleading due to difference in the fabric and structure of the actual soil. Hence strength assessment relies heavily on in-situ testing of soils. The simplified methods suggest using the correlations with the penetration resistance of some common tests i.e. Standard Penetration Test (SPT), Cone penetration Test (CPT) and Tests which estimate Shear Wave Velocity, for obtaining the Cyclic Resistance of soil. The Seismic Dilatometer test (SDMT) has been gaining popularity for its simplicity and repeatability. The DMT is suitable for liquefaction assessments due to its high sensitivity to stress history and aging of soil unlike other tests. The various correlations for assessing the factor of safety using the DMT as proposed by various researchers are discussed. Further the factor of safety by CPT and the DMT are compared at a liquefaction vulnerable area in Gujarat, India. The assessment of factor of safety is done as per the recommended method given in literature, also the liquefaction potential index is evaluated. The results indicate that this site is at a high risk of liquefaction.
