Aconsolidation test on a saturated clay soil gave the following results: cc = 0.2, cr = 0.04, and ocr = 4.5. the existing vertical effective stress in the field is 120psf. a building foundation will increase the vertical total stress at the center of the clay by 80psf. the thickness of the clay layer is 1.5â•›m and its water content is 36%. (a) calculate the primary consolidation settlement. (b) what would be the difference in settlement if ocr were 1.5 instead of 4.5?
