A rectangular pile (0.85 x 0.77) is driven in clayey soil arrangement composed of two different layers. First laye has a height of 9 m., cohesion of 59 kPA, friction factor of 0.84. Second Layer has a height of 5m., cohesion of 74 kPa, and friction factor of 0.87. Compute the allowable load that the pile can carry if the factor safety is 2.37. Use stored value. Answer to 5 decimal places.
A helical pile with 12 in diameter flights and a 2 in square rod is to be installed to a depth of 30 ft in a silty clay. The undrained shear strength is 1,000 lb/ft2 and the groundwater table is at a depth of 40 ft. The individual helixes are located every 5 ft along the length of the pile, and the pile has an average weight of 100 lb/ft (including the embedded soil). Using a factor of safety of 3, determine the ASD allowable uplift capacity, Pup,a.
A square prestressed concrete pile with a 14 inch side is to be driven to the necessary depth. It needs to be able to support 105 kips. It has been determined that the point resistance qp is 120 ksf and the side friction fs is 450 psf. Use formula 12.2 (see attached image) to estimate how long the pile needs to be with a factor of safety of at least 2.5. Round your answer to a multiple of 5 feet. Use L as a variable to calculate the load in formula 12.2. L can be obtained from this equation.
