Behavior and efficiency of perimeter pile groups
Groups of piles are commonly used as high capacity foundations. It is recognised that the load distribution among piles in a group will vary and it is thought that the inner piles are likely to make a relatively small contribution to the total load carried. The essence of the research undertaken is …

Wave forces on cylindrical piles and pile groups : a critical review
… of methods of predicting wave forces on vertical piles or groups of piles. It assigns different force prediction theories to different situations or flow regimes and analyses their advantages and disadvantages. The thesis is split into two sections: Section I reviewing the force prediction methods …

Behaviour of single batter piles and pile groups under lateral soil movement in sand
Piles are commonly subjected to induced loads from nearby construction activities such as approach embankments, excavation, tunnelling and moving slopes. To better understand the mechanism of this complicated soil-pile interaction problem, a comprehensive experimental and numerical program were …

Behavior of Batter Piles in Sand
… of group interaction on behavior of small batter pile groups (3 x 3 and 4 x 4) were examined using the p-multiplier method proposed for the vertical piles. Average values of the p-multipliers appropriate for the small batter pile groups in sand were suggested. Investigations of various …

Investigation of the Resistance of Pile Caps to Lateral Loading
… deep foundations. These foundations consist of groups of piles coupled together by concrete pile caps. These pile caps, which are often massive and deeply buried, would be expected to provide significant resistance to lateral loads. However, practical procedures for computing the resistance of …

Three-dimensional non-linear finite element analysis of laterally loaded piles in clay
Behavior of laterally loaded single piles and pile groups in fine grained soils are investigated using a non-linear finite element methodology. The purpose is to gather behavioral information that would help improve our knowledge of pile behavior and enhance the applicability of some existing …

The axial behaviour of piled foundations in liquefiable soil
… The axial resistance which can be mobilised by piled foundations in liquefiable soils when subjected to strong shaking remains highly uncertain, and a number of piled foundations have failed in strong earthquakes as recently as 2011 . The lack of visible foundation distress in many such cases …

Vibration from underground railways: considering piled foundations and twin tunnels
… effects of nearby embedded structures such as piled foundations and neighbouring tunnels. Through the formulation of computationally efficient mathematical models, this dissertation examines the dynamic behaviour of these two particular types of structures. The effect of the dynamic behaviour …

Foundation response to ground movements induced by tunnel excavation
… of an advancing tunnel excavation on single piles, pile groups and piled rafts. Greenfield displacements are critical input parameters in a two-stage analysis of tunnel-structure interaction. An improved empirical method for the prediction of near-surface tunnelling-induced horizontal …

Dynamic Analysis Of Turbine-generator-foundation Systems
… journal bearings, deck, piers, foundation mat, piles, and soil medium, have been included. Full interaction between the turbine-generator set, the foundation superstructure, and the soil medium, is considered.;A hybrid method is proposed to establish the mathematical model for the …

The effect of vibratory loading on vertical model piles in clay
The results of numerous vibratory tests on model piles in clay are presented in this thesis with the purpose of studying the behavior of piles subjected to vibratory loadings. The effects of pile length, time after driving, soil consistency, dynamic force amplitude, and free water surrounding the …

STUDY OF THE LOADING OF PILES USING A SEMI-ANALYTICAL METHOD AND THE DIGITAL IMAGE CORRELATION TECHNIQUE
The response of single piles and pile groups to axial and lateral loading and the displacements induced in the soil by it are studied in this work using theoretical and experimental approaches. The theoretical solution for the loading of piles is based on idealized displacement forms, energy …

Interação estaqueamento - meio homogêneo
A genral method of solution for vertically loaded pile groups, embedded in an homogeneous linear elastic medium, is presented in this work, with the intention of predicting displacents, rotations and forces distribution along the piles, considering pile-soil interaction. The present analysis is …

An Investigation and Comparison of Accepted Design Methodologies for the Analysis of Laterally Loaded Foundations
Single piles and pile groups are frequently subjected to high lateral forces. The safety and functionality of many structures depends on the ability of the supporting pile foundation to resist the resulting lateral forces. In the analysis and design of laterally loaded piles, two criterions usually …

Theoretical study of the performance of piles.
… have been used to study the manner in which piled foundations deform under working loads. It has been assumed that the soil surrounding the piles may be characterised by suitably chosen elastic constants. This assumption has enabled simple models of the behaviour of single piles under the …

Statnamic Lateral Loading Testing of Full-Scale 15 and 9 Group Piles in Clay
… of seismic and impact loading on foundation piles is an important and a focused interest in the engineering world today. Because of seismic and other natural events are unpredictable, uncontrollable and potentially unsafe it is a vital study to understand the behavior and relationship …
