Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-05 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of many structures need to foundation systems to resist vertical or horizontal pullout 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 pullout 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. 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)

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.

Available in PDF, EPUB and Kindle. Book excerpt: Soil is matter in its own right. Its nature can be captured by means of monotonous, cyclic and strange attractors. Thus material properties are defined by the asymptotic response of sand- and clay-like samples to imposed deformations and stresses. This serves to validate and calibrate elastoplastic and hypoplastic relations with comparative plots. Extensions capture thermal and seismic activations, limitations occur due to localizations and skeleton decay.Attractors in the large characterize boundary value problems from model tests via geotechnical operations up to tectonic evolutions. Validations of hypoplastic calculations are shown with many examples, possible further applications are indicated in detail. This approach is energetically justified and limited by critical points where the otherwise legitimate continuity gets lost by localization and decay. You will be fascinated by the fourth element although or just as it is so manifold.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive guide for the analysis and design of anchor systems used for mooring offshore floating structures. Much of the experience is based on applications toward the offshore oil and gas industry, but the substantial potential for offshore renewable energy systems is addressed. The major types of anchors are described with respect to their basic design concept, advantages and limitations, appropriate framework for analysis, and observed performance. This book addresses all aspects of anchor behaviour related to anchor design including the installation performance, load capacity, deformation, and structural integrity of the anchor itself. Coverage is also provided of appurtenant components of anchor systems, in particular of anchor line/chain mechanics in the soil and water columns. Much of the material presented represents relatively new developments, including several new anchors which have been developed within the last decade, so the book will provide a useful compendium of information is largely scattered in journals and conference proceedings. This book is intended for engineers engaged in offshore geotechnics and marine engineers involved in mooring system and floating structure design. While the analytical methods presented in this text have a strong theoretical basis, the emphasis is on simplified computational formats accessible to design engineers.
