...Shubhrajit Maitra; Yinghui Tian; Mark J. Cassidy The installation of drag-in plate anchors is investigated using advanced large-deformation finite-element (LDFE) analysis. A new modelling technique that can realise the continuously evolving loading angle on the anchor line is described. The entire...

...Y. H. Kim; M. S. Hossain This paper reports the results from three-dimensional dynamic finite-element analysis undertaken to provide insight into the behaviour of OMNI-Max™ anchors during dynamic installation in non-homogeneous clay. The large-deformation finite-element analyses were carried out...

...R. J. Bathurst; Y. Miyata; T. Konami; H. Miyatake This paper reports the results of a novel experiment in which two nominally identical full-scale steel multi-anchor reinforced soil walls were taken to foundation failure by progressive loss of footing support. The 4-m high walls varied only...

...Y. TIAN; M. F. RANDOLPH; M. J. CASSIDY This paper proposes an analytical approach to evaluate the ultimate embedment depth and holding capacity that plate anchors can potentially achieve. Based on a plasticity model for anchor–soil interaction and compatible chain solution, detailed derivations...

...M.S. HOSSAIN; C.D. O'LOUGHLIN; Y. KIM Challenges associated with dynamically installed anchors include prediction of the anchor embedment depth, which dictates the anchor's holding capacity. This is particularly true for calcareous sediments, as very little performance data exist for this anchor...

The long-term axial capacity of jetted conductors was investigated through a series of centrifuge modelling and laboratory thixotropy testing. The centrifuge tests simulated jetting installation of four model...

...C.D. O'LOUGHLIN; M.D. RICHARDSON; M.F. RANDOLPH; C. GAUDIN This paper utilises centrifuge data to explore the penetration response of dynamically installed anchors in normally consolidated clay. The data indicate that for anchors with no flukes, expected anchor tip embedment depths are two to three...

Following a brief outline of the new techniques, stability solutions are given for several practical problems, including foundations, anchors, slopes, excavations and tunnels. © 2013 Thomas Telford Ltd 2013 In geotechnical engineering...

...M.J. CASSIDY; C. GAUDIN; M.F. RANDOLPH; P.C. WONG; D. WANG; Y. TIAN Suction-embedded plate anchors (SEPLAs) have been developed to answer the growing need for anchors to withstand significant vertical loading. The concept combines the advantage of suction caissons (known penetration depth...

...C.C. SMITH A theoretical methodology for determining the range of possible plane-strain limit loads acting on an anchor or trapdoor buried within a non-associative Coulomb soil is presented. Solutions are given for shallow anchors and trapdoors underlying both weightless soil with surface load...

...L. YU; J. LIU; X.-J. KONG; Y. HU Although the pullout capacity of plate anchors in clay has been studied extensively, the results considering the coupling effects of anchor inclination, clay non-homogeneity and self-weight are relatively rare. In the present paper, finite-element analyses...

...D. Adam; R. Markiewicz Ground-embedded structures such as shallow foundations, bored piles, diaphragm walls, tunnel cut-and-cover walls, tunnel linings, anchors for NATM tunnelling and even sewer systems can be used as absorber elements for ground heat exchange. The technology is based on absorber...

...D. J. White; C. Y. Cheuk; M. D. Bolton The design of buried anchors and pipelines requires assessment of the peak uplift resistance. This paper describes a limit equilibrium solution for the uplift resistance of pipes and plate anchors buried in sand. The geometry of this solution reflects...

...J. Kumar; K. M. Kouzer Anchors are often recommended for the foundations of structures such as transmission towers, dry docks and buried pipelines under water to resist uplift forces. Anchors encountered in practice are generally not isolated, and are often placed close to each other. The uplift...

...C. Gaudin; C. D. O'Loughlin; M. F. Randolph; A. C. Lowmass This paper describes a series of centrifuge tests performed in order to investigate the influence of the installation process on the capacity of a suction embedded plate anchor.

...R. S. Merifield; A. V. Lyamin; S. W. Sloan Soil anchors are commonly used as foundation systems for structures that require uplift or lateral resistance. These types of structure include transmission towers, sheet pile walls and buried pipelines. Although anchors are typically complex in shape (e.g...

...C. P. Thorne; C. X. Wang; J. P. Carter The behaviour of horizontal strip anchors buried in clay is examined in this paper. A brief critique of the various approaches suggested for the design of these anchors is presented, with emphasis placed on estimation of the ultimate load that these anchors...

...R. S. Merifield; S. W. Sloan; H. S.
