a certain soil has c'=12 kPa and O'=32°C. The major and minor total principal stresses (0,and 03) = 348 and 160 kPa, respectively, and the pore water pressure at this point is 96kPa. a) Draw the failure envelope and Mohr circle and determine if a shear failure will occur at this point in the soil. Hint: use AutoCAD or Civil 3D to draw two Mohr circles, and the envelope based on scale. b) If so, determine: the angle between the failure plane and the plane on which the major principal stress acts.

Below this is a fairly soft blue-gray silty-clay with an average water content of 30 %. The boring was terminated at 16 m below the ground surface when fairly stiff silty clay was encountered. Make reasonable assumptions as to soil properties and calculate the total, water, and effective stresses at 3, 6, 11, and 16 m below the ground surface.

The soil profile at a site consists of 10 m of gravelly sand underlain by a soft clay layer. The water table lies 1 m below the ground level. The moist and saturated unit weights of the gravelly sand are 17.0 kN/m3 and 20.0 kN/m3, respectively. Due to some ongoing construction work, it is proposed to lower the water table to 3 m below the ground level. What will be the change in the effective stress on top of the soft clay layer?
