Book Description
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. Basic theories on passive pressure in vertical anchor plates Estimation of ultimate capacity in vertical anchor plates Uplift capacity for shallow anchor plates Requirements of vertical anchor plates and design criteria Type and length of inclined anchor plates

Book Description
Soil anchors are primarily designed and constructed to resist outwardly-directed loads imposed on the foundation of a structure. These outwardly - directed loads are transmitted to the soil at a greater depth by the soil anchors. Buried anchors have been used for thousands of years to stabilize structures. Tents are the oldest structures which were stabilized by using soil anchors or stakes. Until the middle of the nineteenth century, soil anchors were primarily used for stabilizing fairly lightweight structures. With the design and construction of large suspension bridges, very large loads were transmitted to the bridge foundation.In order to support these loads, permanent anchoring system in rock medium were gradually developed an constructed. With the development and construction of special lightweight structures such as transmission towers and radar towers, design of special tension anchoring systems for foundations became necessary primarily because the wind load created reactions which were greater than the self-weight of the structures. Soil anchors of various types are now used for uplift resistance of transmission towers, utility poles, aircraft moorings, submerged pipelines and tunnels.Soil anchors also used for tieback resistance of earth-retaining structures, water front structures and buried pressure pipelines to withstand thermal stress. In general at the present time, anchors placed in soil can be derived into six basic categories: anchor plates, direct embedment anchors, helical anchors, grouted anchors, anchor piles, drilled shafts and soil hook systems. The new form of soil anchor used for resisting vertically directed uplifting loads is Soil Hook System (SHS) that can be installed without excavating and grout to the required depth in the ground.

Book Description
Anchors are primarily used in the construction of foundations of earth-supported and earth-retaining structures. The anchors are used in construction to transmit the outwardly-directed load to soil at a greater depth and/or farther from the structure. Although earth anchors have been used in practice for several hundred years, proper theoretical developments for purposes of modern engineering design have taken place only during the past twenty years or so. This book summarizes most of the theoretical and experimental works directed toward the ultimate and allowable holding capacity of earth anchors. The book contains six chapters with detailed discussions on horizontal, vertical and inclined anchor plates, helical anchors, and anchor piles. Discussions on the failure mechanism in soil located around the anchor, as well as various theories to calculate the ultimate and allowable loads, are presented. Laboratory and field test results which are required to supplement and verify the theories have also been included. This book is of interest to consulting engineers in geotechnical engineering, as well as geotechnical engineering researchers and engineering libraries.

Book Description
Soil Reinforcement for Anchor Plates and Uplift Response presents a comprehensive and rigorous review of the current knowledge in soil improvement for anchor plates, and is based on original research that includes experimental data on how to enhance uplift response of soil anchor plates by using several soil reinforcement methods. Divided into 6 chapters, the author makes an introduction to both Ancho Plates and Soil Reinforcement in chapter one, then providing a comprehensive literature review on the topic in chapter 2. Chapter 3 presents how the experiment was set up, the different types of geotextiles used, and the types of soil tested. Chapter 4 presents experimental data, along with data provided by simulation softwares, including Plaxis. Chapter 5 compares the experimental results to the numerical simulation data, providing researchers and geotechnical engineers with tools they can apply to their own projects. In chapter 6, the author presents his conclusions and recommendations on the usage of soil reinforcement to maximize uplift response to anchor plates. Researchers in geotechnical engineering can use the methods and experimental data presented in the book on their own projects, and practicing engineers will benefit from the comparisons between experimental and simulation data provided to make appropriate selection of soil reinforcement techniques that can be applied to their projects. Presents techniques for improving uplift response by 40% or more Discusses the uplift capacity of symmetrical anchor plates in several scenarios Provides a complete review of soil reinforcement for anchor plates Includes numerical analyses methods for validating experimental test results

Book Description
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.
