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
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.

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

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. Researchers such as Mors (1959), Giffels et al (1960), Balla (1961), Turner (1962), Ireland (1963), Sutherland (1965), Mariupolskii (1965), Kananyan (1966), Baker and Konder (1966), Adams and Hayes (1967), Mors (1959), Balla (1961), Turner (1962), Ireland (1963), Andreadis et al, (1981), Dickin (1988), Frydman and Shaham (1989), Remeshbabu (1998), Krishna (2000), Fargic and Marovic (2003), Merfield and Sloan(2006), Dickin and Lama (2007), Kumar and Bhoi (2008), Kuzer and Kumar (2009), Niroumand et al. (2009 & 2011) were concerned with the general solution especially for an ultimate uplift capacity based on experimental works in sand. Also, many numerical studies have been carried out on the behavior of symmetrical anchor plates such as Meyerhof & Adams (1968) until the most recent analysis such as Kuzar ad Kumar (2009) are reviewed. This analysis was pioneered by Vesic (1971),Sarac(1989) and Smit (1989), Krishna(2000), Fargic and Marovic (2003), Merfield and Sloan(2006), Dickin & Laman(2007), Kumar and Bhoi (2008), Kuzer & Kumar(2009) and Niroumand et al. (2011). Increasing use of symmetrical anchor plates to resist uplift response may be achieved by increasing the size and depth of an anchor or the improvement of soil in which these anchors are embedded, or both. In restricted situations, increasing the size and depth of an anchor may not be economical compared with other alternatives. On the other hand, soil improvement can be attained by the inclusion of soil reinforcement to resist larger uplift forces. However, few investigations on the behavior of horizontal plates in a reinforced soil bed under uplift loads were reported. Subbarao et al. 1988 studied the improvement in uplift capacity by using geotextiles as ties to reinforced concrete model anchors embedded in sand. Selvadurai (1989, 1993) reported significant enhancement, of the order of 80 to 100%, in the uplift capacity of pipelines embedded in fine and coarse-grained soil beds reinforced by inclusion of geogrids immediately above the pipeline in an inclined configuration. Krishnaswamy and Parashar (1991) (1994) studied the uplift behavior of circular plates and rectangular plates embedded in cohesive and cohesionless soils with and without geosynthetic reinforcement and reported that the geocomposite reinforcement offered higher uplift resistance than both geogrid and geotextile reinforcement. Ilamparuthi and Dickin (2001) investigated the influence of soil reinforcement on the uplift behavior of model belled piles embedded in sand. A cylindrical gravel-filled geogrid cell was placed around the enlarged pile base. It was reported that uplift response increases with the diameter of the geogrid cell, sand density, pile bell diameter, and embedment. Niroumand et al. (20011) investigated the influence of soil reinforcement and grid fixed reinforced (GFR) on the uplift behavior of model symmetrical anchor plates embedded in sand. This book decries more information on history of symmetrical anchor plates in non-reinforced and reinforced and GFR conditions in sand.

Book Description
Uplift behavior of horizontal anchor plates located near sandy earth slopes with and without geosynthetic reinforcement has been investigated in model tests. Several configurations of reinforcement layers were used to reinforce the sandy soil over anchor plates. Many factors, such as relative density of sand, embedment depths, and the location of the plate relative to the slope crest, along with geosynthetic parameters including size, type, number of layers, and the proximity of the layer to the plate have been studied in a scale model. The failure mechanism and the associated rupture surface were observed and discussed. Test results showed that using geosynthetic reinforcement has a significant effect in improving the uplift capacity of the anchorage plate. However, it was found that inclusion of one layer that is placed resting directly on top of the anchor plate was more effective in enhancing the anchor capacity than reinforcing the slope itself. Based on test results, critical values were discussed and recommended, but should be validated in full-scale or centrifugal model tests.
