Solution:
Which of the following is not a ground improvement technique?
Solution:
When are trapezoidal combined footings required?
Solution:
The ultimate load carrying capacity of the pile group is 5000 kN. Taking the factor of safety as 3, calculate the safe load carrying capacity of the pile group.
Solution:
The gross bearing capacity of a footing is 450 kN/m2. If the footing is 1.5 m wide and at a depth of 1 m in clayey soil with a unit weight of 20 kN/m3, what is the net bearing capacity (in kN/m2)?
Solution:
A 25m deep bored pile has a shaft of diameter 1m and enlarged base of 2.5m diameter in the lower 1.5m depth. The undrained cohesion of the soil varies from 100 kN/m² at the top to 150 kN/m² at the base. Determine the safe load (in kN). Take the factor of safety as 2.5 and the adhesion factor as 0.45.
