An unconfined compression test was performed on a soil sample and the axial compressive stress at failure was 42 psi. a) What is the undrained shear strength of the soil; b) State if this test overestimates or underestimates the field shear strength of the soil. Why? c) Which type of soil is most suitable for this type of test.
3. Data from Unconfined Compression tests on two samples of the same soil is shown in Table 3 below. One of the two samples is an undisturbed sample and the other is remolded. The soil samples were 1.18in in diameter and 3.00in height.

4. Shear Strength A sample of cohesive soil with undrained shear strength of 30 Kpa is beng tested in a triaxial est with a confining pressure of 15 Kpa (see the figure below). Sketch the failure envelope and Mohr's circle representing the state of stress at failure. Evaluate the following: (i) The vertical axial stress at failure. (ii) The major and minor principal stresses at failure (ii) The orientation of failure plane with respect to horizontal plane. (iv) The normal...
soil mechanics Q4:- A sand sample is tested in a direct shear device. The vertical normal stress on the sample is 300 kN/m². The horizontal shear stress at failure is equal to 210 kN/m². a. Compute the angle of internal friction for the sand and the magnitudes of the principal stresses at failure. b. During a consolidated drained triaxial test, a sample of the same sand failed at a principal stress difference of 130 kN/m². Determine the magnitudes of the...

1. During an unconfined compression test on a stabilized petroleum sludge, the following data were obtained. (a) Plot the stress-strain relationship and determine the unconfined compressive strength (USE MS EXCEL). Note that the original sample length was 20 cm and the original sample diameter was 9.1 cm. (b) How many samples could be put vertically without causing a failure problem to the bottom (the first) solidified sample? Load (kg) 0 510 900 1370 1900 2490 3100 3630 3990 4190 4330...
