The standard penetration tests were conducted at a depth of 65 m in the normally consolidated coarse sand deposit

The standard penetration tests were conducted at a depth of 6.5 m in the normally consolidated coarse sand deposit and the blow count was 35. A USA donut hammer was employed in the test. The G.W.Τ. is located at a depth of 4.0m. The unit weight of sand above the G.W.T. is 17.5kN/m3, and the saturated unit weight of sand below the G.W.T. is 19.0kN/m3. a) Evaluate Noo and (N)so, b) estimate the internal friction angle by using both Eq.(3.30) and Eq.(3.31), and the relative density Dr by using Eq.(3.21). A soil sample was obtained by using a standard sampler during the standard penetration test and a mechanical grain-size analysis was performed i the laboratory. The laboratory data are as follows Sieve Size Weight Retained (g) 19.0mm 9.50mm 0 No.10 No.40 No.100 No.200 Pan 158 308 608 652 224 42 8 1.
