An unconfined compression test was conducted on an undisturbed sample of soil with a previously determined shear strength parameter of φ' =29.4°. If the compressive strength was found to be 98kN/m2, determine the pore water pressure at failure for the unconfined specimen. (Δud)f = kN/m2
A drained triaxial compression test on a saturated clay yielded the effective shear strength parameters as c' = 15 kPa and o'= 22°. %3D Consolidated Undrained triaxial test on an identical sample of this clay at a cell pressure of 200 kPa developed a pore water pressure of 150 kPa at failure.

2) Table 1 contains data obtained from consolidated undrained tests on soft clay. You need to determine the shear strength parameters in term of total stress and effective stress. A different specimen of the same soil is also tested in undrained triaxial compression at a cell pressure of 150 kN/m2, and fails when the deviator stress is 75 kN/m2. Calculate the pore pressure in the specimen failure. In your opinion, what is the differences between total stress and effective stress?

A consolidated undrained (CU) compression test was conducted on a saturated clay soil by isotopic allyconsolidating the soil using a cell pressure of 150 kPa and then incrementally applying loads on the plunger while keeping the cell pressure constant. Failure was observed when the stress exerted by the plunger (deviator stress) was 160 kPa and the pore water pressure was 54 kPa. Determine the undrained shear strength of the clay. Determine the undrained friction angle. Determine the drained friction angle.
The equation of the effective stress failure envelope for a slightly over-consolidated clay is 7, = c'+o, tan o . For an axial compression CD triaxial test performed on a sample of this soil at the cell pressure of 96 kPa, the major principal stress at failure was 306 kPa. If c' =12 kPa, determine ø and show the orientation of the failure plane using the Pole Method. Note: give a graphical solution showing all the details.

A soft clay in an unconfined compression test did not develop a failure plane but bulged during the test. The sample was 40 mm in diameter and 85 mm in length. The load carried at a strain of 15% was 70.4 N. Determine the shear strength.
A triaxial test performed on a clay sample, under unconsolidated–undrained conditions, reaches a maximum (failure) axial stress (major principal stress) of 106 kPa when the confining stress (minor principal stress) is 40 kPa. What is the value of cohesion, cu (undrained shear strength) for this sample? If another sample of the same soil is tested in an unconfined compression test, what axial load is expected to cause failure
For a soil, the effective angle of internal friction φ′ was found to be 14° and the cohesion component c′ was 46 kPa. The soil was tested in consolidated drained triaxial condition when the failure stress (σ1 – σ3) was found to be 132 kPa. (a) What was the confining pressure σ3 for this test?(b) Estimate the direction of potential failure planes in the specimen relative to the major principal stress plane.(c) What is the normal stress σf and the shear stress τfon the failure plane in (b)?
Ex A clayey soil specimen was tested in the unconfined compression test. At failure, the unconfined compressive strength (= 100 kPa) and the failure plane inclined at an angle of (50%) with respect to major principal plane. From CD test, the shear strength parameters for the same soil are (30 kPa and 20°). a) Is the soil specimen saturated or not, and why? b) Find the values of shear strength parameters with respect to total stresses. c) Find the value of pore water pressure at failure.
A consolidated undrained triaxial compression test is conducted on a normally consolidated clay at a confining pressure of 75 kPa. The deviator stress at failure is 60 kPa and the pore-water pressure measured at failure is 35 kPa. The effective angle at internal friction of the soil will be
