When finding another location, redesigning a structure, or removing troublesome ground at a project site are not practical options, prevailing ground conditions must be addressed. Improving the ground—modifying its existing physical properties to enable effective, economic, and safe construction—to achieve appropriate engineering performance is an increasingly successful approach. This third edition of Ground Improvement provides a comprehensive overview of the major ground improvement techniques in use worldwide today. Written by recognized experts who bring a wealth of knowledge and experience to bear on their contributions, the chapters are fully updated with recent developments including advancements in equipment and methods since the last edition. The text provides an overview of the processes and the key geotechnical and design considerations as well as equipment needed for successful execution. The methods described are well illustrated with relevant case histories and include the following approaches: Densification using deep vibro techniques or dynamic compaction Consolidation employing deep fabricated drains and associated methods Injection techniques, such as permeation and jet grouting, soil fracture grouting, and compaction grouting New in-situ soil mixing processes, including trench-mixing TRD and panel-mixing CSM approaches The introductory chapter touches on the historical development, health and safety, greenhouse gas emissions, and two less common techniques: blasting and the only reversible process, ground freezing. This practical and established guide provides readers with a solid basis for understanding and further study of the most widely used processes for ground improvement. It is particularly relevant for civil and geotechnical engineers as well as contractors involved in piling and ground engineering of any kind. It would also be useful for advanced graduate and postgraduate civil engineering and geotechnical students.

This book confronts the issue of how young people can find a way into the world of algebra. It represents multiple perspectives which include an analysis of situations in which algebra is an efficient problem-solving tool, the use of computer-based technologies, and a consideration of the historical evolution of algebra. The book emphasizes the situated nature of algebraic activity as opposed to being concerned with identifying students' conceptions in isolation from problem-solving activity.

After years of prosecuting hard-core criminals, rising legal star Alan Bell took a private sector job in South Florida’s newest skyscraper. Suddenly, he suffered such bizarre medical symptoms, doctors suspected he’d been poisoned by the Mafia. Bell’s rapidly declining health forced him to flee his glamorous Miami life to a sterile “bubble” in the remote Arizona desert. As his career and marriage dissolved, Bell pursued medical treatments in a race against time, hoping to stay alive and raise his young daughter, his one desperate reason to keep going. He eventually discovered he wasn’t poisoned by a criminal, but by his office building. His search for a cure led him to discover the horrifying truth: his tragedy was just the tip of the iceberg. Millions of people fall ill and die each year because of toxic chemical exposures—without knowing they’re at risk. Stunned by what he discovered, Bell chose to fight back, turning his plight into an opportunity. Despite his precarious health, he began collaborating with scientists dedicated to raising awareness about this issue. Soon, he also found himself drawn back into the legal field, teaming up with top lawyers fighting for those who had already fallen ill. Both a riveting medical mystery and a cautionary tale, this book puts a human face on the hidden truths behind toxic dangers assaulting us in our everyday environments—and offers practical ways to protect ourselves and our children.
