– For design what do we need to know?

Selection of type of pile,

size of pile, and how to

install it

The capacity of a single

pile

Deep Foundations

CIVL 341 L22: Deep Foundations – Pile Types

The number of piles and

pile spacing required

(accounting for group

effects)

Estimation of settlement

– total vs. differential

– For design what do we need to know?
