- When The Compressive Stress Reaches 27 6mpa A Rock Specimen Is Destroyed And The Included Angle Between The Failure Pl 1 (77.54 KiB) Viewed 32 times
When the compressive stress reaches 27.6MPa, a rock specimen is destroyed, and the included Angle between the failure plane and the maximum principal stress plane is 60°. Assuming that the shear strength varies linearly with normal stress (i.e., following the Mohr-Coulomb failure criterion), Calculate: (1) Internal friction Angle; (2) the shear strength on the plane with normal stress is 0; (3) shear strength on a plane at an Angle of 30° with the maximum principal stress plane; (4) the normal stress and shear stress on the failure surface;
