a) In a geotechnical laboratory an oedometer test on a saturated clay soil was conducted. The results in the laboratory report stated that the Ce-0.2, C,-0.04 and OCR = 4.5. The existing vertical effective stress in the field was 130 kPa. A shallow foundation was designed to construct above the soil condition. This will increase the vertical stress at the center of the clay by 50 kPa. The thickness of the clay layer is 2 m and its water content is 28%. Solve the primary consolidation settlement and determine the difference in the settlement if OCR value were 1.5 instead 4.5.

a)
In a geotechnical laboratory an oedometer test on a saturated clay soil was conducted.
The results in the laboratory report stated that the Ce= 0.2, C, -0.04 and OCR = 4.5.
The existing vertical effective stress in the field was 130 kPa. A shallow foundation
was designed to construct above the soil condition. This will increase the vertical
stress at the center of the clay by 50 kPa. The thickness of the clay layer is 2 m and
its water content is 28%. Solve the primary consolidation settlement and determine
the difference in the settlement if OCR value were 1.5 instead 4.5.
