Problem 2. The soil profile and loading situation from previous homework is shown below. An undisturbed sample was taken at a depth of 10 ft below the original ground surface before the fill was placed Jedi Org SOR CL 20 CL 20 Nort Notice 1. Initial Condition before fill placement 2. Final condition after fil placement You = 130 pcf OCR=1.0 w = 53% G. = 2.67 Yout= 105.8 pcf Double drainage C. = 20 ftyr e. = 1.4 er (after consolidation under fill load) = 1.17 A series of unconsolidated undrained (UU) triaxial tests were then conducted on three specimens of the soil taken from the undisturbed sample. The following results were obtained at failure. Test No. (psf) 01-0_(psf) 1 983 1.200 2 2,984 1,155 3 6,018 1,179 Part 1. Plot the Mohr circles at failure and interpret these data to obtain the undrained strength of the soil, S. Part 2. On your Mohr diagram from Part 1, qualitatively show the expected position of the failure envelope after the CL soil is fully consolidated under the fill load.
