• The ultimate bearing capacity of a pile is defined as the maximum load which the pile carries and continues to sink without any further increases of load
• The safe bearing capacity of a pile is obtained by dividing the ultimate bearing capacity with a suitable factor of safety
• The factor of safety for piles is taken as 6
• All the above.
