Theory and Practice of Pile Foundations
structure load into subsoil and stiff-bearing layer and to transfer impact of
surcharge owing to soil movement and/or lateral force into underlying lay-
ers. They are installed to cater for vertical, lateral, and/or torsional loading
to certain specified capacity and deformation criteria without compromis-
ing structural integrity. They are conventionally made of steel, concrete,
timber, and synthetic materials
We attempt to devise design methods that require fewer parameters
but resolve more problems. This has yielded a systematic approach to
model pile response in the context of load transfer models. This is sum-
marized in this book of 13 chapters. Chapter 1 presents an overview
of estimating soil shear modulus and strength using the conventional
standard penetration tests and cone penetration tests. Chapter 2 pro-
vides a succinct summary of typical methods for estimating bearing
capacity (including negative skin friction) of single piles and pile groups.
Chapter 3 recaptures pile–soil interaction models under vertical, lat-
eral, or torsional loading. Chapters 4 and 5 model the response of verti-
cally loaded piles under static and cyclic loading and time-dependent
behavior, respectively. The model is developed to estimate settlement
of large pile groups in Chapter 6. A variational approach is employed
to deduce an elastic model of lateral piles in Chapter 7, incorporating
typical base and head constraints. Plastic yield between pile and soil (pu-
based model) is subsequently introduced to the elastic model to capture
a nonlinear response of rigid (Chapter 8) and flexible piles (Chapter 9)
under static or cyclic loading. Plastic yield (hinge) of pile itself is fur-
ther incorporated into the model in Chapter 10.
