1.A dry sand is known to have an angle of internal friction of 29. A triaxial test is planned, where the confining pressure will be 41 kPa. What is the maximum axial stress, in kPa, (major principal stress) that can be applied? Calculate the value to 1 decimal place. Do not provide units in your answer. 2.A clay soil is subjected to a triaxial test under unconsolidated-undrained conditions. At failure, the major and minor principal stresses are 8401 psf and 4875 psf, respectively. What is the shear strength of this soil if the confining pressure is doubled? Provide your answer in psf with no decimals.
The stresses induced by a surface load on a loose horizontal sand (ɸ = 30o) layer were found to be σv = 6.0 kPa, τv = 1.6 kPa, σh = 3.7 kPa, and τh = -1.6 kPa. By means of Mohr circles, determine if such a state of stress is safe. If so, what is the factor of safety? Use FS = τff(available) / τf(applied) for the definition of factor of safety.
