end-bearing pile

This feature improves the accuracy of group analysis for end-bearing piles.

A continuous transition from friction to end-bearing piles is accounted for.

A new type of interaction factor, established from subgroups of five piles, is introduced for end-bearing piles.

For end-bearing piles, drilling continues until the borehole has extended a sufficient depth (socketing) into a sufficiently strong layer.

Piles used in this way are, therefore, end-bearing piles as distinct from friction piles, to be mentioned in the next section.
