Geosynthetic Encased Columns for Soft Soil Improvement

The geosynthetic encased column (GEC) is a recent method developed for soft soil improvement, first introduced in the 1980s and first practical applications started in the 1990s. This book provides readers with the fundamentals and practical applications of GEC, including installation methods, design methods, settlement calculations, stability calculations, and field performances. It is aimed at civil engineers, graduate students, and senior undergraduate students.

The geosynthetic encased column (GEC) is a relatively recent method developed for improving soft soil. First introduced as a concept in the 1980s, practical applications began in the 1990s. Over the past three decades, GECs have gained widespread use in certain regions worldwide. However, there is a lack of a comprehensive book in the literature that summarizes the knowledge accumulated regarding this soft ground improvement technique.

The purpose of this book is to provide readers with a comprehensive understanding of GEC fundamentals and practical applications. Chapter 1 introduces the general principles of this ground improvement technique, including installation methods and material property selection. Chapter 2 delves into design methods, encompassing analytical methods for settlement calculations and limit equilibrium methods for stability analysis. Chapter 3 presents calculation examples illustrating the typical steps for service limit state and ultimate limit state designs. Chapter 4 showcases field performances exemplifying practical applications of the GEC technique through case histories. Chapter 5 presents numerical analyses, often used in design to complement analytical methods. Annexes I and II at the end contain the charts developed for settlement calculations.

This book brings together the experiences of four authors with diverse academic and industry backgrounds to describe GEC design and performance. It is intended for civil engineers in general, particularly geotechnical engineers, working in design or practice, graduate students, and senior undergraduate students.
