文档介绍：Preface
Pile design is mostly about application of engineering concepts rather
than use of elaborate mathematical techniques. Most pile design work
can be done with simple arithmetic. I have provided necessary equa-
tions and concepts in a manner so that the reader would be able to
refer to them with ease. All chapters are provided with plethora of
design examples. The solutions to design examples are given in a step
by step basis with many illustrations.
In geotechnical engineering, formulas and methodologies change
significantly from sandy soils to clay soils. I made all attempts to
separate equations based on soil type. Different pile types also would
affect the design methods used. As often the case, one may find mixed
soil conditions. I have provided necessary theory and design examples
to tackle pile design in mixed soil conditions.
This book is mainly aimed at practicing geotechnical engineers,
graduate and undergraduate students who are planning to e
geotechnical engineers. The book should be a great addition to the
civil professional engineer exam in USA or the chartered engineer
exam monwealth countries. This book would also be of interest
to structural engineers and architects who may run into piling work
occasionally.

Site Investigation and Soil Conditions
The geotechnical engineer needs to develop an appropriate game
plan to conduct a piling engineering project. Investigation of the
site is a very important step in any geotechnical engineering project.
The following major steps can be identified in a site investigation
program.
• Literature survey
• Site visit
• Subsurface investigation program and sampling
• Laboratory test program
Literature Survey
The very first step in a site investigation program is to obtain published
information relevant to the project.
Subsurface Information: Subsurface information can be obtained from
the followi
