A soil profile is shown in Figure P3.3 along with the standard penetration numbers in the clay layer. Use Eqs. (3.8b) and (3.9) to determine the variation of cu and OCR with depth. What is the average value of cu and OCR?


Figure P3.3

Dry sand y = 16.5 kN/m3 1.5 m Groundwater table Sand 1.5 m Ysat = 19 kN/m3 Ngo 60 5 1.5 m 8 Clay Ysat = 16.8 kN/m³ 1.5 m * A •8 1.5 m 1.5 m 10 Sand


Eqs. (3.8b)

Dry sand y = 16.5 kN/m3 1.5 m Groundwater table Sand 1.5


Eqs. (3.9)

m Ysat = 19 kN/m3 Ngo 60 5 1.5 m 8 Clay

Dry sand y = 16.5 kN/m3 1.5 m Groundwater table Sand 1.5 m Ysat = 19 kN/m3 Ngo 60 5 1.5 m 8 Clay Ysat = 16.8 kN/m 1.5 m * A 8 1.5 m 1.5 m 10 Sand
