Q. 3. A consolidated undrained (CU) triaxial test was performed on two samples of a clay and the results are: (Note: X is your group Number) : Test No. مربي دبه | Cell pressure (03) (kN/m2) 90 +5X 190 +5X 290+5X Deviator stress (0) (kN/m?) 160 +5X 250 +5X 350 +5X Pore water pressure (u) (kN/m²) 40 95 135 2 a) Draw the Mohr circles and the failure line in terms of total and effective stresses. (Use the EXCEL, see MOODLE). b) Using the Mohr circles in (a), find the shear strength parameters in terms of total stresses (c, Q) and in terms of effective stresses(c', q'). c) For Test2 : What is the normal stresses and shear stresses at failure on failure plane (Of, tt) and (o'f, tf)? d) Using the equations, check your answer in (b) for the case of total stress only. (Use the data from Test1 and Test 2 only). e) Comment on your results.
