A series of vane shear tests have been performed on a soft clay stratum. The results of these tests are as follows: Depth (m): 4.5, 5.5, 7.0, 8.5 Torque at failure, Tf (N-m): 8.9, 10.4, 12.1, 14.2 The vane was 60 mm in diameter and 120 mm long. The soil has a liquid limit of 80 and plastic limit of 45. Find the undrained shear strength (kPa) for each test,

Test for Determination of Shear Strength

The term shear strength is often associated with the soil. Shear strength is defined as the resistance to the deformation of soil particles due to the continuous action of shear stress. In short, shear strength is the maximum shear stress that a soil can sustain.
