A 500 mm diameter and 20 m long concrete pile is driven into the ground. The soil profile at the site consists of 5.0 m of sand ( 35 and y- 19.0 kN/m) at the top, underlain by a thick layer of clay (c,- 50 kPa and y- 19.0 kN/m). Determine the maximum load that can be allowed on the pile with a safety factor of 2.5 Assuming an average Young's modulus of 35 MPa and Poisson's ratio of 0.2...

Q2. A pile group consists of 9 solid floating piles in cohesive soil. Each pile's diameter (d) is 0.50 m and the centre-to-centre spacing (s) is 2.5 m. The subsoil consists of a thick deposit of stiff cohesive clay with an unconfined cohesion of 80 kPa. The total unit weight of soil is 17 kN/m3. The pile group efficiency is 0.83. d 0.5m 1.5m (a) Find the allowable load capacity of the pile group if the required factor of safety...
, calculate the required length and width of a PSC pile to support the allowable load.
You are designing the foundation for a natural gas import terminal. The subsurface is
predominantly alluvial clays in the upper 6 – 15 m below the ground surface (BGS), which
has resulted in large post construction settlements on nearby structures. To prevent large
settlements and differential settlements, the new gas tanks will be supported by pile
foundations. You have determined that pre-stressed concrete (PSC) piles are the most
economical solution. The pile layout will be a square with center-to-center spacing...
