Geosynthetic Encased Columns for Soft Soil Improvement


Book Description

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.

Fundamentals of Geosynthetic Engineering


Book Description

The development of polymeric materials in the form of geosynthetics has brought major changes to the area of Civil Engineering. Increasing interest in these materials and their use has resulted in significant advances in their practical applications in the last few decades. Following this progress, geosynthetics have become a common and favoured construction component in present-day geotechnical engineering. A wide range of compositions is now used, with properties tailored to conditions required for application. Fundamentals of Geosynthetic Engineering provides an overview of the basic concepts of this fascinating and innovative subject area in a logical and illustrative way. This book guides the reader from basic description, manufacturing and material properties of the geosynthetics to their selection process and the major applications. It treats practical analysis and design concepts and provides guidelines for application. In addition, the quality control, field performance and monitoring of applied geosynthetics are discussed, and some aspects of costs analysis are described. The text is supported by examples, multiple choice and numerical questions with answers provided. One separate chapter with case studies is included in the book. In addition, the latest common test standards and codes of practice are introduced in a few sections with extensive references. This textbook will serve courses in geosynthetics or earth reinforcement for graduate students in Geotechnical, Transportation, Hydraulic or Environmental Engineering. It may also be used as part of the undergraduate Geotechnical Engineering course for final year undergraduate students in Civil Engineering. The structure of this text also facilitates self-study by civil engineers, manufacturers and installers who wish to become familiar with the subject matter.




Innovative Infrastructure Solutions using Geosynthetics


Book Description

This book contains contributions on advances in geosynthetics engineering. Soil reinforcement is a very useful technique to construct several cost-effective soil structures in an environmentally friendly and sustainable manner. The most commonly used reinforcement materials are galvanized steel strips, geosynthetics in the form of woven geotextiles, geogrids and geocomposites, and fibers from natural and waste products. In recent years, there have been advances in the area of soil reinforcement, especially in the utilization of the technique in field projects. The researchers have also been working to understand the behaviour of reinforced soil considering the field challenges of reinforced soil structures.
