The geosynthetic encased column (GEC) is a relatively recent method
developed for soft soil improvement. The method was firstly
introduced as a concept in the 1980s and first practical
applications started in the 1990s. GECs have been widely used in
some parts of the world for the last three decades. However, there
is no book in the literature summarizing the knowledge accumulated
during this period in relation to this soft ground improvement
technique. The purpose of this book is to provide readers with the
GEC fundamentals and practical applications. Chapter 1 presents the
general principles of this ground improvement technique including
the methods used for GEC installation and how the material
properties may be selected. Chapter 2 presents the design methods,
thus settlement calculations by means of analytical methods and
stability calculations by limit equilibrium methods are explained
in detail. Chapter 3 presents calculation examples illustrating the
usual steps to be done for both service limit state and ultimate
limit state designs. Then field performances exemplifying practical
applications of the GEC technique are presented in Chapter 4 for
some case histories. Following numerical analyses, often used in
design to complement analytical methods, are presented in Chapter
5. Annexes I and II at the end contain the charts developed to
perform settlement calculations. The book combines the experiences
of four authors with different academic and industry backgrounds to
describe GEC design and performance. It is aimed at civil engineers
in general, particularly geotechnical engineers, either working in
design or in practice, at graduate students, and at senior
undergraduate students.
practically oriented reference volume on soft soil engineering
contains case studies of soft soil techniques from all over the
world New Techniques on Soft Soils covers a wide range of updated
techniques related to site investigation, vertical drains,
surcharge, piled embankment, granular piles, deep mixing,
monitoring and performance. An essential reference for designers
and practitioners involved in soft soil construction, it provides a
comprehensive view of current experiences and opinions of
researchers and professionals from different parts of the world
involving site investigation, design and construction on soft
clays. This book presents a collection of selected expert
contributions on innovations in soft soil engineering, that were
presented at the Symposium on New Techniques for Design and
Construction in Soft Clays held in Guaruja, Brazil, on 22 and 23
May 2010.
