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

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.

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 ultimate and allowable holding capacity of earth anchors. J. Ross Publishing offers a supplemental download — A customizable PowerPoint instructional slide presentation prepared by the authors that complements the material covered in the book, chapter-by-chapter.

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.

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

The design of many structures need to foundation systems to resist vertical or horizontal uplift loads. As part of a larger effort to improve the performance of foundation systems, the development of guidelines for anchor system design and installation. The different structures like transmission towers, tunnels, sea walls, buried pipelines; retaining wall and etc are subjected to considerable uplift forces. In such cases, an absorbing and economic design solution may be obtained through the use of tension members. These elements, which are related to as anchors, are generally fixed to the structure and embedded in the ground to effective depth so that they can resist uplifting forces, will safety. Many researchers have investigated the influence of different parameters on the uplift response of horizontal anchors in sand.

These elements, which are related to as anchors, are generally fixed to the structure and embedded in the ground to effective depth so that they can resist uplifting forces, will safety. The anchors are a thin foundation system designed and constructed specifically to resist any pullout force or overturning moment placed on a structure. Generally, anchors are used to transmit different forces from a structure to the soil. Their strength is obtained through the shear strength and dead weight of the surrounding soil. The different types of anchors used in geotechnical engineering and anchors are including of: Grout system Helical system Plate system Soil hook system(SHS)
