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.

Irregular Shape Anchors in Cohesionless Soils presents a new type of soil anchor that can significantly lower cost and preparation time for application in low cohesion soils. The experimental data provided helps readers design and implement the new devices for their projects.

The author introduces the specific problem of soil anchors in low cohesion soils in chapter one. In chapter two, a literature review is presented comparing findings of previous researchers and positioning irregular shape anchors (ISA) within the most traditional types of soil anchors. In chapter three, the methods used for testing ISA are presented together with the specific properties of sands, anchor materials, and the model of the fracture mechanism. The experimental results are covered in chapter four, including comparisons in embedment ration and sand density. The failure mechanism is discussed both for loose and dense sands. In chapter five, the author compares the experimental data with the theoretical and computational results. In chapter six, the author presents his conclusions and recommendations on the usage of ISA to projects.

Researchers in geotechnical engineering can use the methods and models presented in the book for their own projects. Practicing engineers will benefit from the compiled experimental data and comparisons with most traditional types of soil anchors.

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.
