Following are the results of a standard penetration test in sand. Determine the corrected
standard penetration number, (N1)60, at various depths. Note that the water table was not
observed within a depth of 10.5 m below the ground surface. Assume that the average
unit weight of sand is 17.3 kN/m3.
Depth (m) N60
1.5 8
3.0 7
4.6 12
6.0 14
7.5 13
A soil profile is shown in Figure P3.2 along with the standard penetration numbers in the clay layer. Use Eqs. (3.8) and (3.9) to determine the variation of cu and OCR with depth. What is the average value of cu and OCR?
A civil engineer is interested in assessing the variation of shear strength of clay layers in a site of interest for different depths. After completing CU triaxial tests, the sample mean for the clay shear strength 40 kPa and the standard deviation was 15.5 kPa are obtained for the depth of 3 m from ground surface. For the following conditions:a. Calculate 90% confidence interval (CI) for the population mean μ. Write down your interpretationb. Calculate 95% CI for the population mean μ. Write down your interpretation
