Question The following table gives the variation of the field standard penetration number (SPT) (N60) in...
The following table shows the variation of the field standard penetration number (N60) in a sand deposit. The ground water table is located at a depth of 6m. The dry unit weight of sand from 0 to a depth of 6m is 20.6 kN/m3, use the suitable relationship to calculate the corrected standard penetration number. Also, use the suitable formula to calculate the soil friction angle.
5. An SPT test was performed at a depth of 4 meters below the ground surface and the following values were obtained: 5-8-10 (each value over a 15 cm depth increment). The efficiency of the SPT hammer was measured as 70%. The unit weight of the soil from 0 to 2 meters is 19.7 kN/m3 , the unit weight of the soil from 2 to 3 meters is 18.6 kN/m3 and the unit weight of the soil from 3 to...
An Standard Penetration Tests was performed using an standard sampler at a depth of 45 ft in silty sand of unit weight 125 lb/ft3. The blow counts for the first, second and third 6-inch increment of the test were 8, 13, and 16, respectively. The ground water table at the test location was at 12 ft below the ground surface. The rod length was 15 ft, and the bore hole size was 6 inch Calculate corrected SPT N-value. (I inch-25.4...

Can anyone solve this Geotechnical Engineering question.... I will leave good remarks ?? QUESTION 3 (20 marks) A. Following are the results of a standard penetration test in sand. Determine the corrected standard penetration numbers, (N1), at various depths. Note that the water table was not observed within a depth of 35ft below the ground surface. Assume that the average unit weight of sand is 110 lb/ft! (5 marks) 5 Depth, Z NA 8 10 7 15 13 20 15...
Question 2 The soil profile at a level site consists of a 3-m thick layer of sandy clay, overlaying an 8-m thick layer of loose sand, overlaying stiff gravelly clays that extend to depths greater than 20 m. The water table is at a depth of 2 m and the ground water is initially hydrostatic. The total unit weight of the upper sandy clay, above or below the water table, is 18 kN/m3. The total unit weight of the loose...
Task3 A ten-story building is to be constructed at a site where the water table is at the ground surface. The foundation of the building will be supported on 30 cm diameter pipe piles. The soil investigation at the site and laboratory tests have provided the saturated unit weights, the shear strength values under undrained conditions (average), the corrected SPT values, and the soil profile of the soil to a depth of about 40 m. The soil profile and the...
