In the above figure, the standard penetration test was carried out at a depth of z = 2 m on the sand ground under the foundation base and the obtained SPT N60 value was determined as 21. Calculate the corrected (N1) 60 value at z = 2m depth under the foundation base. At the same time, calculate the elastic settlement in the center of the foundation, the value of Se, using the elastic theory and Hooke's rule on the sand ground in the figure. Take the average Es value for the whole sand layer as 12000 kN / m2. Take the value of the depth factor If as 0.85. According to the results you have calculated, which of the following (N1) gives the values of 60 and elastic settlement, Se.
