a) SPT values are for Er-70 energy ratio. Correct all SPT values by only applying geological overburden correction factor (CN). b) Determine internal friction angle, relative density and unit weight considering effective depth of foundation which will be used in deign. c) Considering corrected SPT values for effective depth, find the bearing capacity of foundation given. d) Determine internal friction angle by using CPT tip resistance values given above for the effective depth of foundation Ø (40p) 2.5m Square foundation Fine sand Y=20 kN/m³ 1m 3m N=16m 3m SPT N=22m 3m N=25 CPT qc=12000 kN/m2 qc=18000 kN/m2 qc=23000 kN/m2 a) SPT values are for Er-70 energy ratio.
