In a standard penetration test in sands, the blow count measured at 14 m depth was 26. An automatic hammer released by a trip with an efficiency of 70% was used in the test. The unit weight of sand is 17.5 kN/m³. Determine: (a) N60 (N1) 60 using Peck, Hanson, and Thornburn (1974) correlation with Pa = 100 kPa. The most likely value of the friction angle (not the range). The possible range of relative density per Peck et al. (1974) The Young's Modulus. The table below presents two correlations proposed for estimating Young's Modulus. kg Leonards (1986) E .cm² E (kPa): = 8N60 = aPa (kPa)N60 Kulhawy & Mayne (1990) In the table a = 5 for fine sands, 10 for clean normally consolidated sands, and 15 for clean over consolidated sands. If a specific method is not specified, you may use any possible correlations. While doing so, you must clearly indicate which correlation was used.

Q2/A standard penetration test was performed in a 150 mm diameter borehole at a depth of 9.5 m below the ground surface. The driller used a UK-style automatic trip hammer, a standard SPT sampler and a 10-m drill rod. The blow counts obtained in the field were as follows: 0-150mm = 4 blows: 150-300mm = 7 blows; 300-450mm = 12 blows. The soil is normally consolidated fine sand with a unit weight of 18.0 kN/m³ and D50 = 0.4 mm. The ground water table is at a depth of 15 m. Compute: (a) N60, (b) (N1)60, (c) D.%, (d) , and (e) denseness of the fine sand.
sand deposit has been identified beneath a site located adjacent to a river. The sand deposit is 15 feet thick and the top of the layer is 12 feet below the ground surface and overlain by a very stiff clay and is underlain by bedrock. The water level has been measured to be at a depth of 10 feet. The standard penetration resistance of the layer has been determined to be 12 blows per foot and a standard sampler was used; a drill rig with a safety hammer with an efficiency of 60% was used. The length of the drill rod is 10 meters and the borehole diameter is 5 inches (127 mm). The design earthquake has been designated as a moment magnitude 6-3/4 event on a nearby fault and the maximum ground acceleration is expected to be 0.40 g. The wet unit weight of the clay soils is 150 pounds per cubic foot and the wet unit weight of the sand soils is 180 pounds per cubic foot.

A 6 in diameter exploratory boring has been drilled through a fine sand to a depth of 19 ft. An SPT N-value of 23 was obtained at this depth using a USA safety hammer with a stan-dard sampler. The boring then continued to greater depths, eventually encountering the groundwater table at a depth of 35 ft. The unit weight of the sand is unknown. ComputeN1,60, f′, and Dr at the test location, and use this data to classify the consistency of thesand.

A vane shear test was performed on saturated clay layer at the site and it is noted that a torque of 45 N-m was required to shear the soil. In order to remould the soil, the vane was rotated rapidly under the certain value of torque say "x". If the sensitivity of the clay is 8, then calculate the value of "x" in N-m. Assume diameter and length of the vane to be 70 mm and 130 mm respectively, consider two way shearing,
