CEEN 641 – ADVANCED SOIL MECHANICS HOMEWORK ASSIGNMENT #8 1. Two consolidated-drained triaxial shear tests were conducted with the following results: Test σ 3 (kPa) σ d (kPa) 1 66 +134.8 2 91 +169.1 Determine the following: a. The shear strength parameters φ and c. Recall that the deviator stress ( σ d ) is equal to ( σ 1 - σ 3 ) and that a positive sign indicates compression. b. The magnitudes of the normal and shear stresses on failure planes for the two soil specimens. c. The orientations of the failure planes for the two soil specimens. (Express your answers as being counterclockwise positive relative to horizontal.) 2. The magnitude and orientation of stresses acting on a soil element are shown on the following page. Determine the following: a. The magnitude of the major and minor principal stresses,
