The Mohr-Coulomb failure criterion was used to calculate the shear strength of the soil by obtaining the cohesion and angle of internal friction from direct shear tests and also by triaxial compress

The Mohr-Coulomb analysis of LHS-1 gives cLHS = 0.311 0.027 kPa and LHS = 31.49 3.67. The same regression analysis of LMS-1 gives cLMS = 0.393 0.035 kPa and LMS = 34.85 4.79.
