Question 01 An undisturbed clay layer is 15 m thick and have a natural moisture content of 45 %. The clay has a saturated unit weight of 17.2 KN/m3, specific gravity of 2.68 and a liquid limit of 65 %. The foundation load will cause an increase of 10 KN/m2 in vertical stress at the bottom of clay layer. Determine the primary consolidation settlement at the point under discussion (bottom), if the ground water level is at surface of the clay layer.
