A 1.5m thick layer of clay is located between 2 layers of sand. At the center of the clay layer, the total vertical stress is of 200 kPa and the pore pressure is 100 kPa. The increase in vertical stress caused by the construction of a structure, in the center of the layer will be 100 kPa. Assuming a saturated soil, Cr = 0.05, Cc = 0.3 and e = 0.9. Estimate the primary settlement of the clay, considered. - Normally consolidated soil - Pre-consolidated soil (OCR=2) - Pre-consolidated soil (OCR=1.5)

Question
A 1.5m thick layer of clay is located between 2 layers of sand. At the center of the clay layer, the total vertical stress is
of 200 kPa and the pore pressure is 100 kPa. The increase in vertical stress caused by the construction of a structure, in the center
of the layer will be 100 kPa. Assuming a saturated soil, Cr = 0.05, Cc = 0.3 and e = 0.9. Estimate the primary settlement of the clay,
considered.
- Normally consolidated soil
- Pre-consolidated soil (OCR=2)
- Pre-consolidated soil (OCR=1.5)
