Anchors are primarily used in the construction of foundations of earth-supported and earth-retaining structures. The fundamental reason for using earth anchors in construction is to transmit the outwardly directed load to the soil at a greater depth and/or farther away from the structure. Although earth anchors have been used in practice for several hundred years, proper theoretical developments for purposes of modern engineering designs have taken place only during the past 40 to 45 years. This book summarizes most theoretical and experimental works directed toward the development of proper relationships for the ultimate and allowable holding capacity of earth anchors. Key Features: A discussion on single-helix screw anchors in sand has been added to Chapter 6 + Two new chapters have been added: Suction and Caisson Anchors (Chapter 9) and Geo-Anchors (Chapter 10) A summary section and self-assessment multiple-choice questions, with answers, are provided at the end of each chapter. + Details horizontal, vertical, and inclined anchor plates, helical anchors, and anchor piles. + Reviews the failure mechanism in soil located around the anchor as well as various theories to calculate the ultimate and allowable loads. + Includes laboratory and field test results to supplement and verify the theories in the book.

Treating anchorages as a direct application of the laws of statics and the theories governing the transfer of load, this book focuses on designs that are safe and reasonably priced. It is divided into two parts. Following a general introduction in the first chapter, Part One goes on to explore anchor systems, components, installation and construction details. Presents special anchor systems such as extractable, compression-type, multibell, and regroutable anchors. Analyzes the transfer of load and its relation to failure modes and anchor load capacity; deals with design considerations; covers mechanisms and types of corrosion; and details anchor stressing, testing programs, and evaluation standards. Part Two considers uses and applications and design aspects of anchored structures; presents design examples of practical value and reasonable simplicity; and incorporates examples and case histories.

This report presents the results of an extensive study of design requirements for anchorage zone reinforcement for post-tensioned concrete girders. The study included a literature review, survey of current state of the art based on an extensive user survey, and a substantial number of physical tests to verify proposed design approaches. Major variables included various anchorage hardware types and degrees of confinement, various types of end anchorage applications (concentric, eccentric, inclined, curved, multiple and with end reactions or lateral post-tensioning), slab anchorages, intermediate anchorages (pocket, blister, and ribs), and diaphragm anchorages. Analytical approaches included strut-and-tie models, finite element analysis, and approximate equations. Correlation between analytical approaches and experimental results was excellent. The report includes recommended design and construction specifications suitable for inclusion in the AASHTO bridge specifications.

Dam and levee remediation has become more prevalent since the start of the twenty-first century. Given the vastness and complexity of the infrastructures involved, keeping up with maintenance needs is very difficult. Major surges in repair are usually triggered by nature’s wake-up calls, such as hurricanes, floods, and earthquakes. The challenge has been to develop methods that ensure safe, effective, reliable, and robust solutions for current and future remediation issues. Specialty Construction Techniques for Dam and Levee Remediation presents the state of practice in North American dam and levee remediation as it relates to the use of specialty geotechnical construction techniques, such as anchors, grouting, cutoff (diaphragm) walls, and deep mixing.

The book focuses on the actual construction processes, describing design and performance aspects of remediation where appropriate. Chapters deal with the application of drilling and grouting methods, methods to install mix-in-place (category 2) cutoff structures, excavated and backfilled trenches (category 1), composite cutoff walls, and stabilization using prestressed rock anchors. The book also provides a comprehensive guide to dam and levee instrumentation, covering planning, operating principles, data management, staffing, and automation. As an educational and salutary example of ineffective efforts, the final chapter presents a case history of a series of remediations performed on a single project, which ultimately proved unsuccessful. A wide range of methods has been developed in response to the challenges that arise in the dam and levee remediation arena and the need for a competitive edge. These new methods are designed and monitored using state-of-the-art techniques, giving rise to the emergence of new intensity and initiative in this field. This book captures this transformation by examining the theory and practice of contemporary remedial techniques, using recent U.S. case histories to provide knowledge and inspiration to readers, both in North America and around the world.

This manual represents the current state of practice in the application of permanent and temporary prestressed rock and soil anchors using high-strength prestressing steel. The recommendations provide practical guidance for the design, installation, and testing of grouted prestressed rock and soil anchors. These recommendations supersede the 1996 edition and include major revisions in the requirements for: -Corrosion protection; -Grouts and grouting activities; and -The use of epoxy-coated strand. Additionally, numerous changes were made to further enhance the understanding of anchor technology. This document is prepared by the PTI Committee for Prestressed Rock and Soil Anchors with input and review by the International Association of Foundation Drilling Anchored Earth Retention Committee.

Primarily designed and constructed to resist outwardly directed loads imposed on the foundation of a structure, anchor plates play an important role in the design of structures (including seawalls, transmission towers, tunnels, buried pipelines, and retaining walls). Design and Construction of Soil Anchor Plates focuses on the various theories based on the design and construction techniques of anchor plates in soil mechanics. The focus of this reference is on design methods, theories, and procedures for constructing permanent or temporary ground anchors and anchored systems. Topics include: General Requirements of Vertical Anchor Plates and Design Criteria, Estimation of Ultimate Capacity in Vertical Anchor Plates, General Requirements of Vertical Anchor Plates and Design Criteria, Type and Length of Inclined Anchor Plates, Early Theories on Anchor Plates in Multi-Layers Soil, and Basic Theories on Passive Pressure in Vertical Anchor Plates. With this reference, researchers and designers will find a valuable guide to the various theories, techniques, and equations for anchor design.

Volume 3 of this handbook deals with foundations. It presents spread foundations starting with basic designs right up the necessary proofs. The section on pile foundations covers possible types of piles and their design, together with their load-bearing capacity, suitability, sample loads and testing. A further chapter explains the use, manufacture and calculation of caissons, illustrated by real-life examples. There is comprehensive coverage of the possibilities for stabilising excavations, together with the relevant area of application, while another section is devoted to the useful application of trench walls. Shore protection is treated in a special contribution covering sheet pile walls, while all types of slope protection and retainments are described in detail with excellent illustrations. Two further contributions are devoted to the special topics of machine foundations and foundations in subsidence regions. The entire book is an indispensable aid in the planning and execution of all types of foundations found in practice, whether for academics or practitioners.
