Irregular Shape Anchor in Cohesionless Soils


Book Description

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. Introduces a new type of soil anchor Offers a thorough literature review on soil anchor types Presents design specifications and practical data that can be used in new projects Provides engineers with a way to save implementation time and costs in geotechnical projects




Design and Construction of Soil Anchor Plates


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

Pullout Resistance of Soil Anchors in Cohesionless Soil Under Varying Velocities by Experimental Methods


Book Description

An examination of the literature in respect to buried soil anchors shows an existing gap in parameters studied. An in depth study on soil anchors subjected to varying pullout velocities has yet to be studied in detail. This thesis outlines an experimental program to test anchors of two different diameters at various embedment depths and pullout velocities using symmetry. The analyzed data suggests the ultimate pullout resistance is rate dependent and is further influenced by diameter size and embedment depth. Anchors embedded at deeper depths with the larger diameter size showed to be more influenced by pullout velocities than those at shallower depths. Therefore, anchors pulled at high velocities should be considered during design process. Furthermore, results from this study can be used to update existing models to account for strain rate effects in addition to validate and calibrate new numerical models to include anchor foundations in potential applications that are subjected to dynamic loading.
