Example 5-5. The data shown in Figure 5.32 were obtained from a series of CU triaxial compression tests on a soft saturated clay in a modern computer-controlled stress-path cell. The samples were isotropically consolidated to confining pressures of 250, 500 and 750 kPa prior to undrained shearing. Determine the critical state parameters N, 2, and M. The raw data from these tests and their interpretation using a spreadsheet is provided on the Companion Website. 400 1.70 1.68 1.66 350 300 1.64 1.62 250 22 V 1.60 1.58 (kPa) 200 150 1.56 100 20 1.54 1.52 50 1.50 0 0 1 10 100 1000 200 600 800 400 p Opal p' kPa) 03 (kPa) After consolidation pi 90 After shearing pl V 90 VI 250 500 750
