7. A 12m long concrete pile with diameter = 0.45m is drilled into normally consolidated clay with S, = 90 kPa and friction angle = 32 degrees. The pile is loaded with 300 kN and in response to such loading, it settles 2.5mm. What is the mobilized short term end bearing resistance? Show your work and circle your answer.
Check the total settlement of a group of pile as shown in Figure 1. The total allowable settlement is set not exceed 3% of the pile diameter and the overconsolidated ratio (OCR) of the clay is more than 1. The groundwater table is located 15m beneath the ground level. The diameter of the pile, b is 0.5m and the spacing between piles, s is 2m.The pile group is subjected to foundation load of 5425kN. The laboratory testing data for the soil samples taken are as follows: At 5m, eo = 0.55, Cc = 0.32, C; = 0.09, o'o = 150kN/m?

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.
