- This paper evaluates the effects of normal load variation, consolidation time and shearing rate on the shear strength obtained by direct shear tests on cohesive soil. The soils were sampled at three different locations at depths of 2 to 3 m such that the in-situ overburden pressures were about 30 - 40 kPa. The normal pressures used in the test are: 6, 12.5, 25, 50,100 kPa; while the shearing rates are: 0.1, 0.5, and 1.0 mm/minutes. The samples were consolidated prior to shearing in the di- :ect shear apparatus. Preliminary test indicated that the average time required for consolidating the sample before shearing is less than l0 minutes. Test results show that normal load variations as well as shearing rate introduce variations in the shear strength obtained by direct shear test. Therefore, it is important that the normal load used for this type of test be comparable with the in-situ overburden pressure and the shearing rate should be calculated based on the time ofconsolidation prior to shearing.
