Comparison In Undrained Shear Strength Between Low And High Liquid Limit Soils

The evaluation of undrained shear strength is very important in geotechnical engineering. This study compares undrained shear strength values of low and high liquid limit soils determined by Fall Cone method and Laboratory Vane Shear Apparatus, based on 16 soil samples with varying liquid limits. The liquid limit of the samples is determined by Casagrande Method and Fall Cone Method. All tests are performed by the same person and same equipments to avoid operator and equipment error. The results indicate that the rate of decrease of undrained shear strength of high liquid limit soils at higher water content is less compared to that at lower water content
