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 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)

Download or read book Symmetrical Anchor Plates in Soil Mechanic written by Hamed Niroumand and published by . This book was released on 2012-02-11 with total page 120 pages. 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.

Book Synopsis Uplift Behavior of Horizontal Anchor Plates Buried in Geosynthetic Reinforced Slopes by : Mostafa A. El Sawwaf
Download or read book Uplift Behavior of Horizontal Anchor Plates Buried in Geosynthetic Reinforced Slopes written by Mostafa A. El Sawwaf and published by . This book was released on 2007 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Earth Anchors written by B.M. Das and published by Elsevier. This book was released on 2012-12-02 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
