A silty sand sample failed during a consolidated-undrained triaxial test at o,=280 kPa and 0,=170 kPa. With the assumption that c=0 and A=0.65, determine the consolidated-undrained friction angle o and a drained friction angle o. If a consolidated-undrained test on such a soil is conducted at a confining pressure o,=340 kPa, what will be major total and effective stresses and the pore water pressure at failure? What will be the maximum shear stress t during a "slow" direct shear test, if the vertical stress o,=160 kPa? cu - 141° 21,0° O,- 560 kpQ 417 RPe %3D 197 RPa T = G1.4 RPa

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.
