Please round to the nearest Hundredth (i.e., 0.01). No Comma! A square pile, 21 m long is driven into a homogeneous sand layer. The pile's width (diameter) is 0.4 m. The standard penetration resistance near the vicinity of the pile is 29. Use FS = 2 and Briaud & Tucker method. Point force, Qp = Skin friction force, Qs = kN kN

A concrete pile with a rectangular shape with a base of 40 cm is built in saturated sand. Find the tension bearing capacity (T) with the ß method. The friction angle between concrete and soil is 30 degrees and k can be calculated with k = 0.5 +0.008D,. 20.00 T Ysat 1 V Sand 20 kN/m³ Yw= 10 kN/m³ Yconcrete 24.5 kN/m³ = Dr = 75% B

FDE 016: A prestressed concrete pile, 400 mm x 400 mm in cross-section, is to be driven in a clayey soil as shown. Use alpha method with factor of safety of 2. Soft Clay 17-15.7 kN/m² c=32 kPa 8 m Stiff Clay * = 19 kN/m² Cu = 90 kPa = 0.5 Refer to FDE 016. What is the end bearing capacity of pile in KN? Select the correct response: 251.84 184.25 129.60 245.32 6 m.

For the (4 x 4) pile group as shown in the figure, the settlement of pile group, in a normally consolidated clay stratum having properties as shown in the figure will be (Load dispersion = 2 H:1 V) mm. 900 kN G Normally consolidated clay Yat = 20 kN/m 6 m w̟ = 40% 8 m w, = 25% e, = 1.05 Hard stratum 250 mm Piles are spaced at 0.5 m c/c.

Determine the diameter of 70 ft long pile driven in the medium dense sand (Shown in Figure). Design load is 185Kips and factor of safety can be assumed to be 2.5. Frictional coefficient is 0.45 Sand y = 115lb/ft3 Ø = 28° K = 0.80 30 %3D Sand 128lb/ft %3! Ysat Ø= 30° K = 0.85 33°C 70

7. If a 45 cm diameter pipe pile is driven into clayey soil to a depth of 12 m. (a) what would the allowable load capacity (Q) be? The water table is 2 m below the ground surface and the soil profile consists of two clay layers (refer to the figure below). Use the ß method to calculate skin friction and the R=30° for all clay layers. (b) Explain how you selected FS value you use. 12 m 9m 2 m 45 cm Y = 18.5kN/m²³ C= 30kN/m² Ysat = 19kN/m³ Cu = 30kN/m² Ysat = 20kN/m² S = 60kN/m²
